I must also add that after X crashes, I see a message on open TTY terminals giving an error message from ipw2200 (the Intel wireless card driver), saying that it can't send SYSTEM_CONFIG, because it's sending a command, or something to that effect. This gets repeated a few times, and visually interrupts anything I might be typing... I'm not sure if this is related to the X crash or not. Is there any workaround I can do? At the moment I don't have a working system at all. Something to change in xorg.conf ? This page helped me a lot: http://bugs.gentoo.org/show_bug.cgi?id=238634 While I haven't been able to stop the regular error messages about "(EE) intel(0): tried to update DSPARB with both planes enabled!" , by disabling compositing (Desktop effects) in KDE4, X seems to be much more stable, and has not crashed so far. Ah interesting, this actually looks like a GL related bug, since you're seeing glx calls in the crash... Any ideas Haihao? Could be an incompatible X server & Mesa build... Are you using mesa7.2? Can you reproduce this issue again? if possible, a full backtrace will help to identify the root cause. How do I generate a full backtrace? (Other than producing the crash again) And what packages do I need installed for that? I'm using Ubuntu. I presume xserver-xorg-video-intel-dbg , and also xserver-xorg-core-dbg ? See http://www.x.org/wiki/Development/Documentation/ServerDebugging for how to use gdb for X crash Ping squid0. Any additional information? Or maybe recent versions fixed the crash for you? Hi Jesse and others. Sorry for the delay. I am happy to say that with updates (I'm not sure exactly which), video is now playing fine on (k)ubuntu. I did find at one stage that mplayer in particular was problematic, so I'm avoiding using it. However, vlc and dragon player play video just fine! :) Great, thanks for confirming. |

Created attachment 19884 [details] Xorg.0.log showing startup and crash I'm using Kubuntu 8.10 (KDE 4) Release Candidate System: Dell D400, Intel 82852/855GM Graphics card. Using only the laptop screen; no monitors or LCD devices attached. X crashes suddenly and unpredictably. Not related at all to what I'm doing; there is no pattern (that I can see) in when the crashes occur. I specifically have not been doing any video, including flash. X logs show numerous issues, from "(WW) intel(0): Bad V_BIOS checksum", issues with memory on the intel driver, and errors to do with pipes and planes: intel(0): Display plane A is now enabled and connected to pipe A. intel(0): Hardware claims pipe A is on while software believes it is off intel(0): Chosen PLL clock of 66.5 Mhz more than 2% away from desired 65.0 M Then, on a pretty regular basis (a few times a minute), the following lines appear, again and again: intel(0): tried to update DSPARB with both planes enabled! intel(0): EDID vendor "IDT", prod id 8902 intel(0): Printing DDC gathered Modelines: intel(0): Modeline "1024x768"x0.0 65.00 1024 1048 1184 1320 768 771 777 803 -hsync -vsync (49.2 kHz) intel(0): EDID vendor "IDT", prod id 8902 Also, after at least about 20 minutes of X uptime (on the times where it doesn't crash before that), I get a KDE pop-up window announcing that a new monitor device has been connected, and offering me to configure it, when I have not connected any monitors at all.
