In this tutorial I’ll introduce you a new project, FSGamer, which can improve full screen gaming in Ubuntu Linux (still in alpha).

FSGamer runs games in their own X server, which can improve the speed, reduce annoying interruptions, and make switching between fullscreen games and your desktop easy and reliable.

To install this tool, click to download the deb and then follow below steps:

1.) First, install from the deb package, assuming it is in Downloads:

sudo dpkg -i ~/Downloads/fsgamer_0.1.1_all.deb

2.) Allow FSGamer to start extra X server:

sudo cp /etc/X11/Xwrapper.config /etc/X11/Xwrapper.config.backup

sudo gedit /etc/X11/Xwrapper.config

then change the line allowed_users=console to allowed_users=anybody.

3.) Allow audio to work in the new X server (change $USER to your username):

sudo usermod -a -G audio $USER

After the previous step, you may have to reboot in order for the audio settings to take effect.

NOTE: This is alpha quality software. It is also very sloppily written, and may crash everything and make you cry. So save your work! :)
