at first I thought is was firefox because it was randomly triggered by clicking on a webpage after it had been running a while. But now it is freezing on the xubuntu 'swarm' splash screen. The cursor moves after the system freezes but nothing else works. ctrl-alt-F# does nothing. the caps and numlock will not even change the lights on my keyboard. i can use consoles if I switch before the splash screen finishes. but as soon as I swich back to gui, its frozen. (i'm making this post via console and elinks. thank yo ubuntuforum webmaster for keeping this page accessable for all)
