Description Tormod Volden 2007-09-02 12:05:19 UTC 
(reported in Ubuntu https://launchpad.net/bugs/136824)
xserver-xorg-core 2:1.3.0.0.dfsg-12ubuntu4
xserver-xorg-video-savage 1:2.1.2-6

"My laptop screen resolution is 1024x768. If I start ppracer with no config file, it will use 800x600 in fullscreen, and this makes the X server crash. If I set 1024x800 in .ppracer/config it works fine. If I change resolution with "xrandr 800x600" before starting ppracer it also works fine."

Same problem has been reported with Savage driver 2.1.3 in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=440839

"When I start dosemu in fullscreen mode X crashes. It does not happen on
other graphics hardware or when I disable the fullscreen feature."
Comment 3 Alex Deucher 2007-09-14 17:21:48 UTC 
This should be fixed in commit: 846a69f70d189c486448df269a512b8d42fab0c2
