I have Ubuntu 10.10 (upgraded from 10.04)
I was browsing in Firefox yesterday, then the PC suddenly did a reset

Once it restarted, everything went normal until gdm begun showing. Then everything froze and locked when userlist showed. I can't move mouse pointer nor do anything with keyboard at this point (just after userlist shows in gdm).

PS: Both, mouse and keyboard work fine, because this Ubuntu is dual-booting with a Windows XP install which loads/works fine.

Here is my .xsession-errors file, but I don't have a clue what may be wrong. Thanks


  • The problem/bug is likely in xorg. Please post links to your xorg.log and xorg.0.log (both files are in /var/log). – papukaija Jan 17 '11 at 19:30
  • I don't have xorg.log ... I only have these: i.imgur.com/zsNbp.jpg and here I've posted xorg.0.log file details pastebin.com/yw4x0ArX Thanks – Enrique Jan 18 '11 at 11:23
  • Same problem with kernel 2.6.38-4-generic on natty. All was working fine before this upgrade. – João Santana Feb 25 '11 at 12:57

Similar things started happening to me after I upgraded to the 2.6.35-25 kernel. That may not be the cause of your problem, but try when you boot selecting the previous kernel version instead (2.6.35-24) and see if the problems go away.

  • Hi edtechdev. I've tried booting with previous kernels from my grub menu, but doesn't help at all – Enrique Jan 18 '11 at 11:29
  • These are my entries in grub. 2.6.36-020636-generic, (same with recovery mode), 2.6.35-23-generic, (same with recovery mode), 2.6.35-22-generic, (same with recovery mode), memory test, and Windows XP... none of ubuntu entries in grub work – Enrique Jan 18 '11 at 11:59
  • My problems (from that kernel upgrade as well) needed a power off and battery remove to reset the graphics card to a stable state. After that, try booting your previous kernel. – Nerdfest Feb 17 '11 at 12:22
