Description Mark McClelland 2006-10-20 09:07:56 UTC
Description of problem:
Whenever I try to start any OpenGL app on this system, the screen freezes as
soon as the app's window appears (presumably the instant the OpenGL surface is
created). If I ssh in, I can see that the "Xorg" process is using 100% CPU. I
can kill -9 it, causing the screen to go black, but I can't get X to work again
without a reboot.

The card in question is a Matrox G400 32MB. I tried it at both 16 and 24 bit
color depth, with the same results.

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1. run glxgears or enable compiz
Actual results:
Screen is frozen until system is rebooted.

Comment 3 Mark McClelland 2006-11-10 05:34:01 UTC
This problem is likely fixed in mga driver 1.4.4 according to

I'll build that version from source tarball and report results here.

Comment 4 Mark McClelland 2006-11-10 07:56:57 UTC
OpenGL is working under 1.4.4 so far. The only problems are that the mouse
pointer disappears and/or leaves a trail of corruption when moved over an OpenGL
surface, and the right side of the screen isn't rendered properly when using
compiz at 1280x1024. IIRC the former problem dates back to FC3 or earlier, and
the latter is probably a 1024x1024 texture size hardware limitation, so I see no
obvious harm in updating FC6 to the 1.4.4 driver.


Comment 5 Adam Jackson 2006-12-11 21:12:08 UTC
1.4.5-2 (resync with rawhide) is headed to fc6-u-t now.

Comment 6 Adam Jackson 2007-01-25 02:20:04 UTC
Pushed to fc6-updates.  I assume it worked, since no one complained...

Comment 7 Hardy Mayer 2007-01-29 17:44:38 UTC
Since updating to FC6 on a system with a Matrox Millenium G200 card, the 
X-display is unusable (I tried several Monitors) -- the problem appeared 
already during the boot from the FC6 iso CD. -- the display is grainy and can 
hardly be read, particularly at 1280x1024. 

Comment 8 Hardy Mayer 2007-01-29 17:48:37 UTC
Hope the update to xorg-x11-drv-mga-1.4.5-2.fc6 will help (I will test the 
machine later today)
