[X1400] random crash when loading the X server

[Pablo Rodríguez]

Binary package hint: xserver-xorg-video-ati

I used other distributions (Mandriva and openSUSE) with the radeonhd driver, but after I switched to Ubuntu 10.04, I experience random X crashes when the video driver is loaded. All I get is a black screen with some random red points at the first lines. I have to restart by turning off the computer and turning on again.

I guess that this is caused by the radeon video driver. Since I had to restart the computer, I have no /var/log/Xorg.0.log to append, since the new one doesn't reflect the crash. I'm not able to provide a full backtrace, because "ulimit -c" was set to 0 (and I wonder whether this setting will support a system restart).

Driver version is:

  xserver-xorg-video-ati:
    Installed: 1:6.13.0-1ubuntu5
    Candidate: 1:6.13.0-1ubuntu5

And Ubuntu version is:

  Description: Ubuntu 10.04 LTS
  Release: 10.04

Is there anything else I need to report the crash? (I don't mind reporting the bug myself upstream.)

Thanks for your help,

Pablo

Hi Pablo,

Please run the command 'apport-collect BUGNUMBER', which will attach several files we need for debugging.

Hi Bruce,

thanks for your fast reply.

Sorry, but I'm afraid I haven't expressed myself accurately.

The issue doesn't appear every time I boot the system (it seems totally random, at least to me) and the computer is totally unresponsive, so I cannot run any command then.

And I guess that if I run when I restart the computer, the files collected by apport-collect might be the wrong ones, since the reboot is fine.

Could you confirm this?

Thanks,

Pablo

Hi Bruce,

I have experienced another crash. I'm attaching the Xorg.0.log file, but I'm afraid it might be the previous one, since the crash happened less than 20 minutes ago and last modification from this file was almost 8 hours ago.

Sorry, I have realized that I don't know how I copied the Xorg.0.log file to the USB memory with Slax, but I'm afraid it is not there. Just in case it might help, I attach Xorg.0.log.old.

I have tried to get a «post mortem» (or «post crashem» ;-)) backtrace, but I'm afraid I cannot get rid of ulimit -c 0.

I have added the following uncommented line to /etc/security/limits.conf:

    root hard core unlimited

But ulimit -c in root is set to 0. This is why I cannot provide a retrospective backtrace.

How can I get core files for the root?

Thanks for your help,

Pablo

Thanks for the Xorg log. We also need the lspci -vnvn output attached to this bug as a file

You've not provided enough information to troubleshoot this bug. The X log you attached does not indicate an X crash. "randomly crashes" does not adequately explain the defect you're experiencing.
