xfree 4 causes screen corruption using mgag200 matrox mystique
Last modified: 2007-04-18 12:29:22 EDT
Xfree 86 4 causes screen corruption in the form of lots of horizontal lines all over the screen as well as some random gray boxes every once in a while. Using 3.3.6 or earlier or turning off acceleration fixes everything. Attached are a startup log for the accelerated config that causes the problems, the config file in question, and my xfree86 3 config file. The x4 i'm talking about is the default for rh 7 and the 3.x in question is the default for 6.2 Just to summarize the logs and config files, my card is a matrox mystique g200 8M and my monitor is a ctx vl700. I upgraded from 6.2 to 7, and made my x 4 config file using Xconfigurator.
Created attachment 4249 [details] my XF86Config-4 file that causes the problems
Created attachment 4250 [details] my x 3 XF86Config that works just fine
changing summary for proper spelling
I'm having very similar problems with an ELSA GLoria Synergy (the 3dLabs Permedia 2 chip). This is on an Alpha system, so it's not just x86. Focussed items begin turning grey or purple of brown... pretty soon the whole screen is that color.
MGA G200 seems to work ok for me with 4.1.0-15 on RHL 7.2 Try upgrading to the latest release. The 3dlabs problem whatever it is is not related to this problem, as it would be video driver dependant.
