Hello all. This howto will tell you how to start a game right from the sessions menu of GDM. I do this because I run Xgl and compiz, and the performance of games while they are running is pretty ******. What this does is instead of starting a window manager, and then starting a game, you can start the game directly. It's extremly easy to do, saves some memory when playing the game, and makes using Xgl/compiz and gaming on the same box much easier. I'm also a memory *****, and figure, if I can save a few megs by not using a window manager at all, why not?
All you have to do is create a game.desktop entry in /usr/share/xsessions . So for example we'll use quake4.
Open a terminal and go to /usr/share/xsessions
Code:
cd /usr/share/xsessions
Use a text editor of your choice and create a quake4.desktop file.
Code:
sudo gedit quake4.desktop
Now create the Entry.
Code:
[Desktop Entry]
Encoding=UTF-8
Name=Quake4
Comment=Start Quake 4 straight
Exec=quake4
TryExec=quake4
Type=Application
And there we go. Restart GDM
Code:
sudo /etc/init.d/gdm restart
and it should appear under sessions.
I Hope this basic howto was at least somewhat usefull. Enjoy
