Title:
  nearly every other boot I get "Low Graphics Mode" message.

Status in “xorg” package in Ubuntu:
  Confirmed

Bug description:
  I'm not entirely sure that this is xorg, I can't figure out which log file to look in to find out. The log files with likely names did not give me usefull info.
  I've seen similar errors, but never the same hardware or circumstanses.

  Behavior started immediatly after upgrade to 12.10

  I'm running GNOME classic (though I think this bug is occuring before
  this becomes relevent), using an ATI HD4850 video card with open
  source drivers.

  About every other boot, I get a white message box telling me that something went wrong and the system will boot in low graphics mode. I'll try and write down the exact message next time this happens.
  The first time this happend (the next day after upgrading to 12.10, I was able to select the "use defaults" option to continue. every time after this, the "use defaults" or "use latest backup" goes right back to the same question. The only way forward is to boot into low graphics mode.

  I usually shut down the computer at the login screen when it is in low
  graphics mode (from the menu, not the switch), and turn the computer
  back on. This has booted cleanly with the correct graphics mode every
  time I have done it (about 4 times). The one time I tried "sudo
  shutdown -r now", it rebooted and had the same problem again
