This looks like a hardware issue. Could you please choose at boot memory test and let it run. If you got errors there is a serious hardware problem like corrupted mem or something like that.
Do you have another operating system to recheck if this problem happens too?
Which Ubuntu version do you use and could you please attach the output of 'lspci -vvnn' in a file?

at the moment I use Hardy for testing, here is output of lspci.
I check the mem now and report the result ;)

Does this crash only happen with Hardy and not Gutsy or similar?
Could you please attacht the following information?

Detailed list of steps to reproduce

How complete is the X failure?
+ Does ctrl+alt+f1 take you to a console?
+ Does ctrl+alt+backspace restart X?
+ Does mouse pointer still move?
+ Does the keyboard LED come on when hitting the CAPSLOCK key?

/etc/X11/xorg.conf
/var/log/Xorg.0.log
~/.xsession-errors
output of cat /proc/acpi/video/*/DOS
output of sudo cat /proc/acpi/dsdt

With Gusty there is still no Problem.
Okay the problem is, i can't reproduce this failure, sometimes it happens between switching applications
in the taskbar, or only touch to the touchpad :/

1. ctrl+alt+f1 works for 10 seconds, then the console is blank too!
2. ctrl+alt+backspace doesn't work
3. Blank screen, no mouse
4. yes, the keyboard is working

there is only one way, switch to console and press ctrl+alt+del to reboot the system.

I have the same issue with very similar Xorg.0.log.old output.

I guess it is the best to get a backtrace https://wiki.ubuntu.com/DebuggingXorg of the crash. The hardware state message isn't so rare according to some searches. Btw. please make sure that you have all updates installed.

@ar
Could you please attach your data too and create a backtrace?

Augusto (augusto.rendon) wrote : Re: [HARDY] X crashes randomly (i915)

I don't seem to find a core dump in either /etc/X11/core or in /var/crash/ so not sure how to get the backtrace. I followed the changes in https://wiki.ubuntu.com/DebuggingXorg, i.e.:
changed the file /etc/default/apport to enabled=0

and added

Section "ServerFlags"
        Option "NoTrapSignals" "true"
EndSection

to my xorg.conf

I attach the Xorg.0.log.old

The description of the problem is identical to wuddiwupp's

thanks

You have to use gdb to get a backtrace from Xorg like described in https://wiki.ubuntu.com/DebuggingXorg and you need another machine to log in remotely.

same error here on my thinkpad x41 (intel 900).

We will not be able to begin troubleshooting this issue without a backtrace. The directions on https://wiki.ubuntu.com/DebuggingXorg explain how to do this; you may need to ssh into the box after it has crashed in order to connect gdb to the Xorg process.

I have connected remotely to the broken machine.
After starting gdb, the command attach <pid> never completed
Tried Ctrl-C, with no effect
Xorg was meanwhile eating up 100% cpu.

thanks.

I have the same problem in Macbook with Intel 945GM. The crashes seems to be random :(

Am confirming this, I've been seeing frequent, similar X crashes with my 945GM/GMS/GME. It seems to triggered for me with things like opening a video or alt+tabbing but I've seen it crash, like the original reporter said, when doing nothing. I'll try and get a backtrace next crash.

Same bug here but with an nvidia card... So not related to Intel card.

Oh by the way, I've found a temporary workaround...
ctrl+alt+backspace doesn't work, but alt+super+k can kill the x server and from there I can start a session again.

I've seen that receiving files in gaim triggers that bug too.

I'm sure if it's the same bug, but opening a video in totem seems to 'freeze' X about 50% of the time currently.

jon1012: even if you have problems with nvidia doesn't mean that it's the same bug. This is clearly intel-specific.

Thanks for collecting the backtrace. Unfortunately, it doesn't show any calls except this one, so isn't of much use:

0xb7f71410 in __kernel_vsyscall ()

Maybe we'll upstream it and hope they can offer better advice for how to troubleshoot this one.

Bryce Harrington (bryce) wrote :

In looking at this bug report further, this isn't upstreamable; there's no error messages and no steps identified to reliably reproduce the issue. So without a valid backtrace there is nothing that can be investigated.

Leaving at Incomplete until someone can provide a better backtrace.

Note that to get a backtrace you need to run 'bt full' at the (gdb) prompt. It looks like in the above backtrace this was not done, which is why the backtrace is so incomplete.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
