Keystroke Visualizer

Keystroke is a Qt based keystroke visualization tool for Linux. This is a new KDE project just created a few days ago. It is helpful when creating screencasts where you want to show what you are typing. E.g. when using vim.

See the video:

This keystroke visualization tool only works on K Desktop Environment (KDE). For Ubuntu users, you can easily install it by running the commands below one by one in terminal (Press Ctrl+Alt+T to open the terminal):

sudo add-apt-repository -y ppa:samrog131/ppa

sudo apt-get update

sudo apt-get install keystroke

This will install the tool in (K)ubuntu 14.04, (K)ubuntu 13.10, (K)ubuntu 12.10, and (K)ubuntu 12.04.

Once installed, search for and run keystroke-gui in the start menu and then type anything to see the magic!

This simple tutorial shows how to upgrade your system from Ubuntu 13.10 Saucy to Ubuntu 14.04 Trusty Tahr for both Desktop and Server editions.

Ubuntu 14.04 Trusty is scheduled to be released on April 17th. At the moment of writing this article, the alpha release is available to upgrade in Saucy’s updater for testing purpose.

Important: Production machines please wait until the Ubuntu 14.04 final is released. By then, we can follow below steps to upgrade our systems.

Before starting any upgrades, you need to:

  • Backup important files, documents, bookmarks and other data.
  • If you’ve manually installed proprietary drivers directly from the manufacturer’s website, then before upgrading I recommend removing these drivers first and reverting to the open-source drivers
  • Open Software & Updates utility from Unity Dash. Disable all third-party repositories under Other Software tab.

Desktop Upgrade:

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run the commands below to update your system:

sudo apt-get update; sudo apt-get dist-upgrade

Now start the updater via -d option:

sudo update-manager -d

The Software Updater will open and tell you your system is up to date and a new release Ubuntu 14.04 is available.

Click on the Upgrade button and confirm again in next window. Software Updater will fetch and install the files and prompt you to remove unnecessary applications.

Finally you’ll be asked to restart your computer to finish the upgrade. That’s it.

Upgrade Ubuntu Server:

NOTE: Please backup your configuration files if you’re running any services on Ubuntu server.

For Ubuntu Server edition, we need to install the update-manager-core first by executing the command below:

sudo apt-get install update-manager-core

Then edit the config file:

sudo vi /etc/update-manager/release-upgrades

Make sure there’s a line that says “Prompt=normal” or “Prompt=lts”.

Start the upgrade process by:

sudo do-release-upgrade -d

Follow the on-screen prompts and you’re done!.

Since Ubuntu 13.10, there’s an indicator applet on top panel which allows to quickly switch between keyboard layouts for various languages.

If you find that the keyboard indicator is useless, you can easily remove the applet from top panel by following the steps below:

1. Open System Settings from Unity Launcher or from top-right corner shutdown menu. Then click on Text Entry

2. In the bottom of the window you’ll see “Show current input source in the menu bar” which is enabled by default. Uncheck the box and the indicator applet will disappear instantly.

That’s it. Enjoy!

Want to control screen brightness through an indicator applet on panel? Well, you may want this app if your Fn key does not work properly.

Brightness indicator allows to change screen brightness by using the indicator menu or the scroll wheel of your mouse over the indicator icon. It’s inspired by the original Gnome brightness applet.
