Description of problem: When switching from graphics mode to textmode by hitting CTRL-ALT-F1 the system locks up. The screen stays black, the monitor does not audible click as it does when normaly when switching to textmode and if some kind of sound is currently playing it loops. Version-Release number of selected component (if applicable): xorg-x11-6.7.0-3 How reproducible: Always The problem is always reproducible, however, I can't link it to some specific action. Sometimes it happens after several hours of uptime, sometimes after a few minutes. The problem does present itself on different systems with different graphic hardware (Matrox G400, a Matrox G400DH and a ATI Rage 128) leading me to believe it is not related to a specific kind of video adapter. Is there any advice on how to sucessfully debug this problem? After the system hangs I do not get any useful data in the logs.
Please attach your X server log from after a crash/problem. Be sure to make a backup copy of the log before starting up the X server or the new invocation will overwrite the old log from the crash. Also attach your config file and /var/log/messages. Each attachment should be using the link below, and uncompressed. Thanks in advance.
The X server log is useless as the crash prevents any error from being written to the log. Config file is attached. However, it seems that xorg-x11-6.7.0-5 fixes the problem, which seems to be: * Sat Jun 26 2004 Mike A. Harris <mharris> 6.7.0-5 - Fixed bug in mga driver which caused hangs on some Matrox Mystique boards of revision 0->2, which were caused by a previous upstream bugfix for another issue. xorg-x11-6.7.0-mga-storm-sync-fix.patch (#124028) I'll do some further testing however to make sure the crashes really disappeared.
Well. The crashes still occur. The update didn't change anything as it first seemed. Attaching /var/log/messages config and Xorg.0.log, although I do not see anything useful in them.

skipped attaching /var/log/messages as it says nothing short of mentioning that the kernel is booting because the box was rebooted after the crash.
Have you tried testing with a serial console? Is the crashing graphics hardware AGP or PCI? Did the problem happen with any previous Linux distributinos? If not, try installing a Red Hat 9, Fedora Core 1, White Box Enterprise Linux, CentOS 3.x, Tao Linux, or Red Hat Enterprise Linux kernel (you may need to edit /etc/X11/xorg.conf to use /dev/psaux instead of /dev/input/mice again, if you are using a PS/2 mouse)? (You should be able to install one of those kernels using "rpm -ivh --oldpackage name-of-kernel.ix86.rpm".) OBTW, even if the final crash information isn't getting into /var/log/messages, attaching it may be helpful anyway! Even if you can't see anything useful in it, somebody else might. :) It may also be useful to attach "/sbin/lspci -vvxxx" output from *all three* affected machines. (Doing it from all 3 may show us some kind of common link between the machines.)
Nope. No access to a serial console until now. I will test it however. The Matrox G400 is only available as AGP. No the systems worked flawlessly with _each_ single version and beta up to and including FC1, starting with RH6.0 or so... I'll try a different kernel however... There is no accessible crash information in the logs. None as in, nonexisting, not as in not-recognizable by me. :-) The system crashes before anything can be written to the syslog. lspci output is attached.

I have the same problem with an radeon 9200 running in xinerama mode. If I turn the xinerama off the problem goes away. BTW, the system-config-display won't turn the xinerama back on once turned off (lucky for me I had my original xorg.conf saved :-). Attaching my xorg.conf

I had the same problem on FC3 with a Matrox G400. The computer had previously been running Mandrake Linux 9.0 (with a 2.4 series kernel), without any problems. With FC3, the system would completely lockup when switching from graphical mode to text mode, or when running system-config-display. There was nothing useful in the system logs as the system would completely freeze before anything was appended to the log. I tried updating everything to the latest version, but to no avail. As a last resort, I updated the bios on the graphics card and miraculously this solved all my problems. http://www.matrox.com/mga/support/drivers/bios/home2.cfm Hope this helps.
