Description Adam Pribyl 2006-02-04 09:38:18 EST
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20060202 Fedora/1.7.12-1.5.2 Description of problem: I saw there is few other bugs about udev-071. I have following problem after update to udev.i386 071-0.FC4.2 with Matrox G200 card. It seems that with this udev version kernel loads matroxfb on X startup. As far this could be nice, as long as I want to use matroxfb and it does not cause any other troubles. But in this case it does. When X is starting and also matroxfb is loaded the screen remains blank in init 5, leaving user without any clue what's wrong. Switching to Alt+F1 shows FB console, switching back to Alt+F7 shows X login. Using kenrel option "nofb" or "video=matroxfb:off" is useless as this module is most probably loaded by udev. I do not find any way how to disable fb loading. I may be wrong this is cause by udev, but it is deffinitely not due to kernel update - others only KDE and mozilla stuff were updated, so these I do not expect to cause it. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Update to udev 071-0.FC4.2 2.Have matrox g200 3.start to init 5 Actual Results: Blank screen. Expected Results: X login screen. Additional info: These are messages from kernel, they were not present before udev update: Feb 4 15:29:12 localhost kernel: matroxfb: Matrox Millennium G200 (AGP) detected Feb 4 15:29:12 localhost kernel: PInS memtype = 5 Feb 4 15:29:12 localhost kernel: matroxfb: MTRR's turned on Feb 4 15:29:12 localhost kernel: matroxfb: 640x480x8bpp (virtual: 640x13107) Feb 4 15:29:12 localhost kernel: matroxfb: framebuffer at 0xDD000000, mapped to 0xe1480000, size 8388608 Feb 4 15:29:12 localhost kernel: Console: switching to colour frame buffer device 80x30 Feb 4 15:29:12 localhost kernel: fb0: MATROX frame buffer device

Adam, this problem seems very similar to what Fred New reports in Bug #179041. What happens if you try the workaround Fred tried in Bug 179014 comment 12?
Comment 2 Adam Pribyl 2006-02-04 11:52:46 EST
Are you sure you meant bug #179041? It is about "i810 video and generic LCD are not dectected during install" reported by Seth Doty and there is no comment 12.
Comment 3 Adam Pribyl 2006-02-04 11:57:10 EST
Oh I see it is typo in second link. It is really #179041 and it seems similar except it is different video card and I do not have any signs of X starting, simply monitor clicks few time and leave black. If thats not matrox specific I am aware this is common problem of simultaneous inicialization of FB and X.
