I have Ubuntu 10.10 (upgraded from 10.04)
I was browsing in Firefox yesterday, then the PC did a suddenly reset
Once I restarted, everything went normal until gdm begun showing. Then everything froze and locked when userlist showed. I could not move mouse pointer nor do anything with keyboard.
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
