Description of problem:
When full screen games (such as SuperTux or Supertuxkart) are launched, X dies
and it goes to a command line. Then it will go back to gdm where logging in will
work and X will be fine. Sometimes X doesn't load back up and I have to
manually restart my machine. If I open a game in a windowed mode, it works
perfectly. glxgears also works, with FPS in the 12000s. Oddly, Sauerbraten
(http://sauerbraten.sourceforge.net/) works if I launch it (./sauerbraten_unix),
and also works when I use the commands to set height (-h) and width (-w). (The
full launch command would be ./sauerbraten_unix -w1440 -h900 for me)
Version-Release number of selected component (if applicable):
7.1.1 (70101000) (according to my kmod-nvidia driver)
Happens every time I launch a full screen game.
Steps to Reproduce:
1. Install a game that uses widescreen if one isn't installed (yum install
supertux for example)
2. In the Gnome menu, go to Applications > Games, and choose SuperTux
X will crash, then will go to a non-graphical command prompt, and then goes to
the gdm login screen as if nothing happened.
SuperTux opening without crashing anything.
Running widescreen (1440x900) with a nVidia 7800GS using kmod-nvidia.i686
version 1.0.9629-22.214.171.124_1.28 from the Livna repo. I've tried switching to
1024x768, and got the same results (using the same monitor and same video card)
Attached is my /var/log/Xorg.0.log. Desktop effects are not enabled during the
time I launch the games.
