My system freezes regularly, more than once a day, sometimes right after the start of X. I have not been able to reproduce the error deterministicly.

After rebooting, where do I find the old files? Which are most likely to be relevant?


  • My system is a desktop computer.
  • According to temperature measurement, there is no overheating.
  • I currently use a 32-bit OS. Recycled the drive of my old computer.
  • Linux 3.2.0-23 generic (i868)
  • Intel Core i3-3225
  • 8 GB RAM - no errors according to ram test on first 4 gb.
  • Gigabyte h77-d3h mainboard (ivy brigde)
  • No graphic card installed
  • 350 W power device.
  • I use an old dvd-drive together with an whatever2sata-converter.
  • The LAN box of my machine does not react, so I suppose the mainboard is defunct, but I want to be sure.

Thanks for reading.

Run: sudo dmesg to see recent kernel messages. – kenorb Mar 2 at 22:55

It depends on the error. For X-related errors, files of interest are:


You may also find useful information about various errors (not only X) in

/var/log/messages           <-- general status/error reports
/var/log/pm-powersave.log   <-- power management reports

and in the files in /var/log in general. Is this a laptop? Is your system overheating?

/var/log/Xorg.0.log seems only to contain information from my current uptime. – shuhalo Jun 21 '13 at 16:44
Your question regarding overheating might touch the point. I use an external w-lan stick via usb, and it seems that the freezes correlate with the usb-stick turning palpably warm. – shuhalo Jul 1 '13 at 12:29
