Description Whay-Wang Teo 2006-02-15 21:08:39 UTC 
Hi,

I have the same bug that is the same as on https://bugs.freedesktop.org/show_bug.cgi?id=2168

I'm not sure if I'm using the same version of X11 but I am basically running the MGA driver with the option NoAccel to avoid screen corruption.

Could you add /var/log/Xorg.0.log? Thanks.

The Xorg0.log file

Thanks for looking through the bug
Comment 5 Stefan Dirsch 2006-02-17 07:37:47 UTC 
> (--) PCI:*(2:5:0) Matrox Graphics, Inc. MGA 1064SG [Mystique] rev 2, ...

So changing it to "... pMga->ChipRev < 2)" might indeed help. I'll attach you a driver for testing later.

Please give it a try (copy it to 
/usr/X11R6/lib/modules/drivers/).

Could you please test?
Comment 9 Whay-Wang Teo 2006-02-17 17:42:00 UTC 
tested with the sax2 program. the problem is fixed. now i don't need a new graphics card. :-) thanks for the help.
Comment 10 Stefan Dirsch 2006-02-17 17:50:58 UTC 
Still needs to be fixed for 10.1.
Comment 11 Whay-Wang Teo 2006-02-17 18:16:26 UTC 
hi i forgot to mention that this is in /usr/X11R6/lib64/modules/drivers/ for 64 bit systems

but i guess thats common knowledge. guess this bug fix would be in the future suse X server packages
Comment 12 Stefan Dirsch 2006-02-17 18:24:16 UTC 
Yes, of course this is now fixed for all supported architectures since SUSE 10.1.
