Install Awesome Window Manager 3.5.5 in Ubuntu 14.04

Last updated: June 27, 2014

Awesome is a dynamic window manager for the X developed in the C and Lua. It aims to be extremely small and fast, yet extensively customizable and make it possible for the user to productively manage windows with the use of keyboard.

Awesome has emerged as a dwm fork featuring customization through external configuration files. Although highly extensible, the default setup of the window manager is deliberately simplified. In doing so, the author has created what he calls a framework window manager for users to expand and adapt to their own needs.

Install The Latest Awesome 3.5.5 in Ubuntu 14.04:

While Ubuntu repositories contain Awesome 3.4.x, you can get the last features and fixes by installing v3.5.5 from an unofficial PPA.

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

sudo add-apt-repository ppa:klaus-vormweg/awesome

sudo apt-get update

sudo apt-get install awesome

Once installed, log out current session and choose log-in with awesome.

Enable Onscreen Keyboard in LightDM-Gtk-Greeter in Ubuntu 14.04

Last updated: June 26, 2014

 

If you’re using Lightdm-Gtk-Greeter instead of the default Unity Greeter in Ubuntu 14.04, this quick tutorial will show you how to enable onscreen virtual keyboard in your login screen.

Lightdm-gtk-greeter provides a light-weight, GTK+2 or GTK+3 login screen for Linux desktops. It is available in the Software Center of Ubuntu 14.04.

Onscreen keyboard is not enabled by default in this greeter. If you want this feature, just do a little tweak on the config file and then you are able to launch the virtual keyboard via indicator menu or shortcut key F3.

First edit the config file, /etc/lightdm/lightdm-gtk-greeter.conf, with your favorite text editor. Here I use gedit.

Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, run:

sudo gedit /etc/lightdm/lightdm-gtk-greeter.conf

When the file opens, do:

  • add new line keyboard=onboard
  • add ~a11y; as a value of indicators

So the file will look like this:

Finally save the file and reboot. Enjoy!
