Red Hat Bugzilla – Bug 197033
X doesn't work anymore with Matrox G400
Last modified: 2007-11-30 17:11:36 EST
Description of problem: X starts but I only see "waves" on screen. I tried the command 'system-config-display --reconfig' but still doesn't work. So I'm using vesa driver to get a reasonable 1024x768 display.

Created attachment 131644 [details] Xorg after starting with mga driver
Just recompiled mga driver from FC5 SRPMS ( xorg-x11-drv-mga-1.2.1.3-1.2 ) and installed it. Works like a charm !
> X starts but I only see "waves" on screen. What do you mean? For me, the monitor is switched off when using the "mga" driver. VESA mode 800x600 works, but is inacceptable.
After building FC5 xorg-x11-drv-mga-1.2.1.3-1.2 for Rawhide (Jul 18th) I end up with a working mga driver again. At least these are broken: xorg-x11-drv-mga-1.4.1-4 xorg-x11-drv-mga-1.4.1-4.1
If you disable AIGLX and restart does the problem change at all?
FWIW, my xorg.conf doesn't mention AIGLX anywhere, only the "glx" module. So I queried Google, landed at a confusing place in the Fedora Wiki, which covers installing AIGLX from source and things like that, but didn't find any concrete/good documentation on how to enable/disable it at the server-level. Then I decided to move on. And disabling "glx" didn't change anything. One thing I might try later is recompiling the new driver with less optflags.
Recompiling xorg-x11-drv-mga-1.4.1-4.1 without optimisations didn't "fix" anything either.
Will FC6 ship with a broken mga driver?
Have you tried running X -configure and then copying the generated file in place of the s-c-display generated file? I had severe problems with out of range before using the X -configure generated file. I only had to reduce the Vertical refresh range from a suprising maximum of 190 Hz to top out at 70 Hz to be conservative. With the FC5 xorg.conf file generated by s-c-display, I got an out of range error when loading the game viruskiller. This config file did not do this with Xorg-x11 from FC5. Filed a bug report recently. Bug 207804
Jim, "X -configure" lead to a very questionable 1600x1200 resolution and a monitor that created a frightening bad smell in the office while displaying a black screen with a mouse cursor. Nothing I would want to look into further. Seems highly dangerous to me. [...] system-config-display is broken again, too. (-> different ticket) With this real bad experience and the /dev/null symptoms here in bugzilla I can only discourage any Matrox card users from trying Fedora Core 6. :-(
(In reply to comment #6) I may be this is new in wiki: http://fedoraproject.org/wiki/RenderingProject/aiglx#head-936632a0253a7a1e6c04e697932546dde44175c1
Checking the "I am providing the requested information for this bug" once more a original reporter is not responding and communication has stalled.
Reply to comment 11: In the log (**) Option "AIGLX" "off" (**) AIGLX disabled makes no change. Symptoms stay the same. Blank screen, monitor is put to sleep.
Provided xorg.conf is obviously modified from the original one. Let's stop panicking, and start diagnostics: move away your xorg.conf and reconfigure from scratch. You only have 16Mb videoram - try not pushing your card to 1024x768. Do you see the same behavior with 800x600? Stop complaining and try to provide more symptoms than just "blank screen". You didn't do your job in this bug report, but you want someone else to dance around you...? Don't even try to tell me that if xorg.conf worked before, it was not broken. No such compatibility is ever guaranteed.
