Experience Dell G7 17 – 7700 with Ubuntu

2. October 2021 by Marcoin AllgemeinLeave a Comment

I bought a Dell G7 17 – 7700 in April 2020. After now half a year, I would like to present my experiences with this laptop here.

Requirements

First, I would like to briefly discuss my requirements. These were:

Linux compatibility. The thing should simply run. I have little desire to fiddle around a lot during installation. I want to install Ubuntu and good.
Usable battery life. It’s important to me to be able to work on the train for a few hours when I’m traveling. I don’t need a laptop that can last a whole workday without power. Most of the time my laptop resides on my desk anyway.
A good keyboard. If you have to work with the laptop directly on your lap, then the keyboard should be comfortable to type on. I personally like keyboards with a short stroke.
Neat memory. Since I work a lot with React and Webpack, and have many browser windows open, I need quite a bit of memory. 16 GB is actually the absolute minimum, 32 GB is probably better.
Large hard drive. The same goes for the hard drive, in the end it should probably be a terabyte, so that you don’t use up all the space right away with virtual machines and a few videos.
17 inch display. I personally like 17 inch (about 43 cm) laptops. They replace a second monitor on the desk and when you also have them on your lap, they don’t wreck your neck and shoulders as much as smaller models.
Neat workmanship. The laptop should already have a certain value. I don’t need a model made of full aluminum, but it shouldn’t look like a lunchbox in the schoolyard either.

With the above-mentioned requirements, I first went on a search. The many cheap devices that are available in the 17 inch class were already ruled out, since the keyboard and case are usually of subterranean quality.

Unfortunately, the devices from Linux-specialized providers were also not for me. Their 17-inch laptops are mostly white-label gaming laptops that are very heavy, very thick, very expensive and look quite cheap.

Let’s get one thing straight: I’m a big fan of Linux-focused vendors. I would buy a desktop PC from such a vendor any day. Unfortunately, laptops are not made of standard components like desktop PCs, and therefore, it is very difficult for niche vendors to develop their own laptops

After some research, I came to the conclusion to buy a gaming laptop that is not designed for absolute maximum performance, but rather for casual gamers. Gaming laptops usually have decent hardware built-in and have a usable keyboard, because gamers have to hack into the keys all the time.

I decided on the Dell G7 17 – 7700 because it has a slightly raised display, which I thought would give me a small ergonomic advantage when working on my lap.

Installation

After about 7 days the laptop arrived at my home. The first thing I did was to test the Ubuntu suitability with a live stick. After a few minutes without any problems, I went to the installation. I threw down Windows and installed Ubuntu 20.04.

I simply took the default settings from the Ubuntu installer. Good as I am, I also turned on the hard disk encryption.

After a short time, the installation was fixed and ready. The G7 and was thus ready for use and could also be used already well

By the way, I didn’t change anything on the BIOS but left the factory settings as they are.

Rework

Where there is a lot of light, there is also shadow. It was possible to start working with the G7 directly after the Ubuntu installation. But nevertheless, there were a few small things that needed to be optimized.

The Nvidia driver installed by default by the Ubuntu installer didn’t work with my multi-monitor setup. I have two other monitors at my workstation beside the laptop monitor that I connect to, once via USB, once via HDMI. With the proprietary Nvidia driver, it simply did not work to address more than one monitor.

Since gaming is not a priority for me, I looked around for other solutions. My first idea was to use the open-source Nouveau driver. And to my luck, this one worked right away. Its advantage is that it fits much better into the Ubuntu/Gnome settings

The worse performance with graphics-heavy applications doesn’t matter much to me

Besides the problems with the graphics card, only the fingerprint reader was not working. However, I didn’t bother with it any further.

Screen

The Full HD screen is very bright and you can even work in the sun without problems. The maximum resolution is 1920 x 1080.

Battery life

I am quite satisfied with the battery life. It’s certainly enough for a train journey. I don’t need to be able to use my laptop all day without charging it. 5 to 6 hours are always possible with normal use.

Keyboard & touchpad

The keyboard and touchpad are the secret highlights of the G7. The key travel is very low, which I personally like, and works buttery smooth

The large touchpad is made of glass and is very pleasant to use. Unlike cheap laptops, you glide over the surface very easily. The multitouch support with Ubuntu is at least sufficient for my requirements.

Conclusion

In conclusion, I have to say that I am very satisfied with the G7. It was a real stroke of luck for me. The device is powerful enough, looks good, and has very good ergonomics.

Windows Survival Guide for React and Web Developers

23. May 202015. January 2021 by Marcoin Rockiger Blog

Introduction or why I wrote a survival guide

As a lifelong Linux user I started a job in a company where I had to use a Windows laptop. My job is to create a React frontend. Not knowing Windows I wondered about the best way to do my development work.

2 Routes

During my research I discovered two ways for emulating a Linux/macOS like workflow in Windows.

The first way creates a minimal bash environment to emulate a Linux command line. You will run Windows alternatives of your development tools.

The second route uses the Windows Subsystem for Linux 2 (or short WSL 2) to create a Linux environment inside your Windows system. This way you can use all your Linux tools like in your Linux distro. On the downside it uses more system resources and needs more work to set up.

Which route to choose?

If you have admin rights to your Windows machine and prefer Linux over Windows I would recommend going with WSL.

Fast Route

Pros:

easy to setup
doesn’t need admin right
uses fewer resources

Cons:

it doesn’t have to full power of a Linux distribution
your dev-environment will probably differ from your prod-environment
IO-operations with Yarn/NPM are slower

The fast route works fine for developers who want to get started quickly or don’t have admin rights on their development machine. It will imitate a Linux or Mac dev-environment with a package manager for Windows called Scoop.

The apps we install later are selected because they work without admin rights. For that reason I opted to install Node.js directly instead of using nvm-windows which needs admin rights to set the default node version.

To start, open a PowerShell and install scoop first. Paste the following lines in your PowerShell:

set-ExecutionPolicy RemoteSigned -Scope currentUser
Invoke-Expression (New-Object System.Net.WebClient).DownloadString('https://get.scoop.sh')
 # If you get an error 'https is not supported try typing it by hand. Windows screws up URLs.
scoop help
 # for usage information
scoop search # this will show all available packages
scoop search git # this will show all available packages with git in their name

Now that we installed scoop, we can install our dev-environment:

scoop install git
scoop install nodejs-lts
scoop install yarn

Now it’s time to test our dev-environment. Assuming you come from a Bash background, it makes sense you are using Git Bash now, which was installed with git automatically. Open up Git Bash and create a React app:

git install https://github.com/GermaVinsmoke/bmi-calculator.git # If you get an error 'https is not supported try typing it by hand. Windows screws up URLs.
cd bmi-calculator.git
yarn # this will take some time
yarn start # this should start your default browser on http://localhost:3000

Bonus: Installing an editor

Assuming that you don’t want to use notepad or vim for your development. It makes sense to install a different editor. Therefore we need to add another repository (called bucket) to scoop, then we can install most editors available (Atom, VScode, Notepad++).

For fans of Jetbrains products there is an additional bucket called jetbrains.

scoop bucket add extra
scoop install vscode # or notepadplusplus or atom

If you are using Git Bash it makes sense to restart it, because otherwise the editor will not available in your path. Other than that you are now good to go.

Rockstar Route

Pros:

dev-environment is the same as the prod-environment
has access to all Linux tools
very fast IO with NPM
can even run Linux GUI programs

Cons:

uses more system resources
needs more work to set up

Check if you have the right windows version

If you want to install WSL 2 you need Windows build 18917 or higher. You can check your Windows version with the shortcut Win+R and enter winver in the entry field. If you don’t have a suitable build you need to join the Windows Insider Programm in your Settings. I recommend the Slow track, where you get updates about once a week.

Install WSL2

First, we need to enable the Windows Subsystem for Linux and enable the Virtual Machine Platform.

Open a PowerShell as administrator:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux # is this really needed
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

Restart your system.

Install a Linux Distribution (Assumes that you install Ubuntu)

First set WSL 2 as default. In a PowerShell enter:

wsl --set-default-version 2

After that, go to the Microsoft Store and search for the Linux distro you like. I will assume you chose Ubuntu.

Open the Ubuntu from the Start menu and create a new user. The full installation of Ubuntu will need a view minutes.

When the installation has finished, update the packages.

sudo apt update && sudo apt upgrade

Now you have a fully functional Ubuntu at your fingertips. And can install your development tools analog to our solution above.

By the way, if you want to open your current Ubuntu directory in Windows just type:

explorer.exe .

An Explorer window will open on your screen.

Install VSCode on Windows

To develop comfortably on Windows you should install VSCode on Windows. I personally had problems with the Scoop version. So install the version from their website.

Similar to the file explorer you can then open Ubuntu directories with

code .

Install NodeJS and Yarn on Ubuntu

Open up an Ubuntu window and enter the following code to install Yarn

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt install yarn

Then install NodeJS with Node Version Manager.

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
source ~/.bashrc
nvm install --lts

Use Linux tools to develop

Now you should be able to use the development tools you need. To test your new environment try

npx create-react-app my-app
cd my-app
yarn start

A browser tab should open and you are able to start developing.

Which way to develop do you prefer? Let me know if you are interested running Linux GUI programs with WSL 2.

33 Linux Apps You Will Love

11. February 201815. January 2021 by Marcoin Rockiger Blog

Starting with Linux on your laptop and want to know which apps you should use? Or you want to find better alternatives for the apps you already use? This guide gives you apps for almost everything you need on a Linux machine.

I have listed apps I use personally on my Linux laptop – they are a mostly open source, all free of charge and completely awesome.

To install these apps refer to your distro’s package manager.

Right now I have no apps included for tasks I don’t need to do. For this reason there is no video editor app and no instant messaging – feel free to add them in the comments. Also, I didn’t include websites I use, like Google Calendar and Gmail – tell me
if you want me to cover them.

I also didn’t include apps that are usually an integral part of your Linux distribution like your desktop environment and your file manager. Personally, I like KDE, but the apps I listed work great with any desktop environment.

Internet

Firefox

Firefox is the free web browser of the Mozilla project. It has a lot of extensions to customize your web experience and feels more lightweight than Chromium.

Chromium

Chromium is the free variant of Chrome. It is a slick web browser with a minimal user interface and tons of extensions. Unlike Chrome, it doesn’t come with Flash and closed source codecs. A nice feature is
that you can save a specific website to your application menu.

THUNDERBIRD

Thunderbird is the free E-Mail-Client from Mozilla. Like Firefox, Thunderbird is very customizable and has a lot of extensions.

Office

LIBREOFFICE

LibreOffice is the office suite for Linux. All alternatives leave a lot to be desired for serious work. Since it’s fork from OpenOffice LibreOffice’s development pace is growing steadily. If you are searching
for OpenOffice, use LibreOffice.

TYPORA

Typora is a very sleek looking Markdown editor. Unlike most other Markdown editors it has no preview window the edit view, but a What You See Is What You Get interface.

StarDict

StarDict is a dictionary app that can access different dictionaries. I use it to look up German words. To do that, you mark the words you want to translate. A pop-up window will appear. A Qt-alternative is GoldenDict.

Text Editors

Visual Studio Code

Similar to Atom VSCode is built with web Technologies. You can customize VSCode to your liking and extend it with a great amount of add-ons. VSCode feels faster and less resources hungry than Atom. On the downside, its user interface is less polished than Atom’s. Contrasts and headings are too small in my opinion. A good example of that is the search form.

ATOM

Atom is a text editor created with web technologies. It is very customizable, has a lot of extensions available and should be more familiar to a new user than Emacs. On the downside, it is quite heavy on your system’s resources;
especially if you are using a lot of extensions like I do.

EMACS

Emacs is an extensible, customizable editor from the GNU project. It is probably the most powerful text editor there. On the other side, emacs started in 1984 and therefore has a lot of idiosyncrasies. This is why
the learning curve is steep. I recommend looking into Spacemacs or ErgoEmacs for easing the experience.

Todo-List

AKIEE

This is a shameless plug; I am the author of Akiee, but I really think Akiee is one of the best task managers out there. It is based on the Kanban method and makes it easy to prioritize your tasks and on concentrating
on what to do next.

ORG-MODE

Org-Mode is a special mode in Emacs that gives you the possibility of note-taking, planning and outlining. Many say it alone makes it worth to learn Emacs. For people who don’t use Emacs, it is a considerable time investment
to learn Emacs and Org-mode.

Note-Keeping

ZIM

Zim is a personal wiki that makes it very easy to keep your notes. It makes it very easy to connect and organize your notes. It comes with several extensions for your documentation needs.

LEO

Leo is an outlining application, that looks very interesting for people who have to write a lot of text. Use it for note-taking, outlining and even literate programming. Like a lot of powerful tools, it needs
some time to get into it.

BASKET

Basket is a very potent note-taking application. It comes with a lot more features than Zim but has a steeper learning curve.

FREEMIND

FreeMind is a powerful Mindmapping software that is easy to use and available for all major platforms. If you are into Mindmaps, FreeMind is for you.

Developer-Tools

VIRTUALBOX

If you need a virtualization solution on your desktop VirtualBox is the easiest way to get one. There are other solutions for Linux, but they are not as easy to use.

SMARTGIT

SmartGit in an easy to use, full-featured Git GUI. It is not open source but free for personal use.

Security

KEEPASSX

Using a password manager is probably the number one action you can do to improve your security on the Internet. KeePassX is the best working solution for me so far.

Multimedia

VLC

VLC is one of the most famous multimedia players out there. And for a reason. It plays almost every kind of multimedia file. If you have trouble with your pre-installed media player give VLC a try.

SPOTIFY DESKTOP

Spotify desktop is not a great piece of software, but if you are a Spotify user, there is no better option out there.

Graphics

GIMP

Gimp is your solution for an in depth-graphics editor for Linux. It can do most things Photoshop can do. Most people need to get used to the user interface if they come from other graphics software.

INKSCAPE

Inkscape is a vector graphics editor, that you can use for professional designs. It has flexible drawing tools, can import a lot of file formats (including pdf) and has a powerful text tool.

SCRIBUS

Scribus is a professional desktop publishing system to create booklets, brochures, magazines and everything that’s printed.

Education

ANKI

Anki is an intelligent flashcard app, which makes it easy to repeat and to remember things. With Anki, you can learn much more efficiently languages and facts.

Games

STEAM

Steam is a distribution platform for computer games. You can get about 160 commercial games for Linux on Steam. If you want serious gaming on Linux, you need Steam.

FROZEN BUBBLE

Frozen Bubble is a cute and colorful logical game. It has a high-quality soundtrack and can be quite addictive.

FREECIV

FreeCiv is a free and open source Civilization clone. If you like the original, you will like Freevic.

Productivity

CLIPIT

ClipIt is a lightweight clipboard manager. If your desktop environment doesn’t have one included like Gnome, you definitely should use one. It will do wonders for your productivity.

ALBERT

Albert is a productivity app that will boost your efficiency for launching apps, searching files, browse your bookmark and even calculate simple arithmetic.

AUTOKEY

AutoKey is a desktop automation utility. It allows you to manage a collection of scripts and phrases, and assign abbreviations and hotkeys to these. AutoKey will enable you to execute a script or insert text
on demand in whatever program you are using.

QTerminal

QTerminal is a very lightweight tiling terminal emulator. Its highlight is that you can create multiple planes by splitting them into any layout you want. QTerminal is very practical if you need several terminal
windows open. Gnome, Xfce, Ubuntu and Mint users can use Tilix, that is better integrated with their desktop environment.

Yukuake

Yukuake is a terminal that drops down from the top of the screen when pressing a specific shortcut. Yukuake is very useful if you want to type a short command in your terminal without opening
a new window on your desktop. Gnome, Xfce, Ubuntu and Mint users can look at Guake, that is better integrated their desktop environment.

SYNERGY

Synergy is a special tool you can use to share the mouse and keyboard of different computers. Just go to the edge of your computer with your mouse pointer and move it seamlessly to your next computer – like a
second screen.

Emulators

Wine

Wine is a Windows-compatible runtime environment for Linux. That means you can run a lot of Windows-software on your Linux machine. I use it to run an old version of OpenOffice that I need for using a particular German
spell checker.

PlayOnLinux

PlayOnLinux is a graphical user interface for Wine. It makes it much easier to install software and administer different Wine versions.

Financing Open-Source-Projects via the Ubuntu Software-Center

23. December 20114. April 2017 by Marcoin Rockiger BlogLeave a Comment

Financing Open-Source-Projects via the Ubuntu Software-Center

Since a few month it's relatively easy to offer commercial software through the Ubuntu Software-Center. Why shouldn't this be used to finance open-source projects like the Gimp, Ardour or Openshot and support their development efforts.

Let's Take Brian Lunduke's favorite example: The Gimp. Before I want to make an fundamental assumption: It doesn't conflict with the open-source/free software idea, to sell software, if you publish the source code at the same time.

How could this look like?

For Gimp there are certain plugins, which are not available via the standard package sources and which maintenance is bugging the typical (web-) designer.

Why not offer certain plugin packs in the Ubuntu Software-Center for a fair price? For example, I could imagine a plugin pack, that makes a preselection of special plugins for photo post-production – with features that are not available in Shotwell.

This could be an opportunity for the Gimp team; who's got more competence about Gimp than the Gimp team itself. What's true for Gimp is also true for a lot of other applications like OpenShot, Ardour, Open-Office, etc.

Where is the customer value?

Most OSS users are bugged or simply overstrained by the installation of plugins, PPAs or the compiling of source code – regardless they like to use the best plugins and the newest software. It would be arrogant to say: users should develop theses skills or wait for 6 – 24 month until the next version of Ubuntu comes out.

The concept of providing updates via the Software-Center is especially interesting for LTS-versions of Ubuntu. Users and programmers get totally new possibilities bypassing missing updates by Canonical.

Why it is important to have a vibrant commercial Ecosystem around open source software

Many times open source projects, most often small ones, have to fight obstacles like new hardware or server costs – not to mention compensation of the team members. In addition, most open-source projects are developed by solo developers and are lacking manpower to have faster development cycles.

If you are now interested in developing business ideas around open source software, check the two articles:

How do you think about it? Should open source projects try to raise money with the Software-Center?

Positioning Linux In The Desktop Market (or Why Hendrix would have used Linux)

28. July 20104. April 2017 by Marcoin Rockiger BlogLeave a Comment

Would he have used Linux? by furibond

At the moment some people are telling us Linux would have finally lost the battle for the desktop. For justification they claim Windows 7 is overtaking the netbook market. In this essay I will argue, Linux has not lost the desktop market and it should not position itself in the low-end PC market but in the high-end.

Linux can not lose the desktop market.

As I said before, Linux can not be beaten in the market as long there are curious programmers all over the world contributing to Free Software. For the success of Free Software it is not important how many people are using it. It is important how many people are contributing to Free Software. This argument stays true for big projects, like Gnome and KDE, and for all the small projects, like Scribes, Impressive, Gnome-Do, etc., that make Open Source Software so exciting.

Linux is build as a high-end system

Linus Torvalds created Linux because there were no suitable Unix-like operating systems that he could afford. That's why he build an operating system he would find "beautiful". In conclusion it is fair to say that Linux was build as a high-end operating system. The coincidence that Linux is running on such a variety of devices is just a sign of its class and the advantage of the OSS development model.

Linux competes with OS X

Fender Stratocaster by daves_place

Linux is created to be an Unix and not a DOS. If you compare operating systems to electric guitars Linux is a Fender Stratocaster. It is hard to learn but very rewarding. Windows in contrast is a Guitar Hero game controller. It is nice in the beginning but the possibilities are very limited and it hampers your creativity. Personally I think the real competitor to Linux is OS X. OS X would be a Gibson Les Paul. Very good lookin', a bit easier to play, but very expensive and not as versatile as a Strat. Like the guitars from Fender and Gibson, both operating systems have some things in common, but differ in certain aspect, especially in philosophy. The biggest similarity of the both operating systems is that they are both Unixes.

Some philosophical differences between Linux and OS X

open source vs. closed source: If you want, you can use the sources of Linux as you wish. Learn from, change it or rip it apart an build something totally new out of it. In the sense of Google's informal corporate motto "Don't be evil!" Apple is the devil. If you mess with Apple's software you could end up having a lot of fun with their lawyers. total freedem vs. a bit more guidence: Linux lets you digg very deep into the operating system. They user, if he is admin too, has total control over the system. By Design you can totally rebuild your system. OS X doesn't give you as much freedom, on the other hand you are not as likely to screw something up with your system.

The future of Linux is very bright.

A well fed penguin

Besides that Linux has a very robust business model and as such is here to stay on the desktop, I think Linux should be sold with high-end desktop PCs and laptop and should not be used on low cost hardware. It excels with high-end hardware, especially when used by talented people. Linux is a product for power users who want to use their computers to boost their creativity and create new exciting things. As Alan Key said:

The computer is simply an instrument whose music is ideas.

Now it's your turn. What is your opinion on that? By the way Hendrix mostly played the Stratocaster.

Linux Users Are Software Pirates

27. July 20104. April 2017 by Marcoin Rockiger BlogLeave a Comment

Why are Linux Users Software Pirates?

In one sentence: Linux users are software pirates, because they don't pay for their software. Period!

We all talk about the awesomeness of Linux, Ubuntu and Open-Source-Software, but who of us is willing to pay for OSS? Nobody! Everything has to be free of charge. But Linux and OSS is about freedom, not free beer! We, who want everything for free, aren't any better than those who illegally leach software and games.

Why this is a fucking problem!

Software for Linux sucks!

Tell me about one high-end graphic suite, tell me about one state of the art game, tell me about one top business software!

It's hard to believe, writing awesome software is hard work; anybody who works hard has to eat and sleep, otherwise she will die. Sometimes this developer wants to take care of his family – strange thing.

What is the consequence for the average open-source developer?

Surprise: She goes to work.

What doesn't she do, when she is working? Exactly, she can not continue work on her open-source project.

Let's reference Brian Lunduke and take a look at The Gimp:

To make The Gimp competitive to Photoshop the project needs 3 developers and 1 tester. If everybody earns 75 k, what is not much for decent developers, the project needs about 300 k in funding! There a no marketing efforts or anything else included. Just the money for the developers, that they can eat and will not die and will finish the project.

If we want killer open-source-apps, we have to pay for it – it is just this simple!

What can we do?

Donate! Donate! Donate!

Unfortunately, we all donate to infrequently and we donate to small amounts – myself included.

If we agree, that open-source users have to donate, then we should ask the following question:

How and how much should we donate?

Donating a little amount for every project doesn't make much sense, therefore I suggest a five step action plan:

Forget the big distros, the Linux kernel and other company backed projects – they have enough money.
Now think about it: Without which software you couldn't live anymore? Which project do you need for your job? Make a list.
Write down your top 5. My list looks like this:
Now imagine: somebody takes your top 5 hostage. How much ransom would you pay? What is your personal value for each program in your top 5? Take this amount and write it behind the corresponding program in your list.
Donate! Yeah, you're right, the different amounts you have written down, this is what you donate. The great thing is, you can donate whenever you want. For example, after your next big customer project is finished and you earned a ton of money – but remember: With freedom comes responsibility!

To say it again, if you donate you are just fair. If you are don't donate you behave not much different than a software pirate, that found a legal loophole.

I know the temptation to do nothing is great, but get yourself together – do something!

The perfect vocabulary trainer

26. July 20104. April 2017 by Marcoin Rockiger BlogLeave a Comment

Most of us have trouble to learn vocabulary, technical terms or facts. But why is that? Because we don't repeat things we learned often.

Mnemosyne helps

At that point comes Mnemosyne to the game. Mnemosyne works like an intelligent vocabulary trainer. Who knows what to repeat when you should repeat it.

If you want to memorize something Mnemosyne is your perfect match. For example, add some vocabularys. Mnemosyne will test you on that words and you will have to grade your answer. Mnemosyne will then try to estimate the next time it test you on that words.

Tipps

I use Mnemosyne to:

learn Englisch words that I don't know, when I'm on the internet
memorize facts from a textbook.

ghotkey – Set Hotkeys in gnome easily

25. July 20104. April 2017 by Marcoin Rockiger BlogLeave a Comment

This is a little Python program I wrote. It lets you set the 12 Metacity (the gnome window manager) hotkeys for any application you like. Set any command you like in the left entry field of a row and the corresponding hotkey in the right entryfield. The format for the hotkeys looks like "<Control>a" or "<Shift><Alt>F1". The parser is fairly liberal and allows lower or upper case, and also abbreviations such as "<Ctl>" and "<Ctrl>". If you set the option to the special string "disabled", then there will be no keybinding for this action.

You all know the shortcuts <Ctrl>+c, <Ctrl>+v and <Ctrl>+x to copy and paste content from the clipboard. If not you should change that immediately. A great disadvantage of the standard clipboard is, if you want copy different text passages you have to change between the source and the target back and forth. Parcellite creates an history of the clipboard for you.

Install It

Download the package, install via the GDebi installer and add it to your autostart list.

Use It

A mouse klick on the applet or the shortcut <Ctrl>+<Alt>+h Parcellite shows you the last 25 clipboard entries and you can choose one.

You can paste this entry as usual via <Ctrl>+v. A typical use case would be, if you want to use a certain text passage several times, but want to work as usual without switching back to the original source all the time. It needs some time to use Parcellite effectively. Discover the opportunities and rock Ubuntu today.
