Hi, IMHO, this is NOT a duplicate of bug #553789 : maybe the symptoms are the same, but I experience it with the intel driver (with an intel graphic card.
It happens to me sometimes when I try to open a word document in libreoffice (but I can't swear it's always the case). When it happens, everything on the screen is frozen, the keyboard doesn't react (even the shift lock doesn't toggle the led). The mouse can still move on the screen but can't click anything. The hard disk still works so it's not a kernel panic. The power button doesn't work, ctrl alt backspace doesn't work. The only thing I can do is hard reboot. I am running Ubuntu 11.04. This is my uname -a : Linux olivier-Latitude-E6420 2.6.38-11-generic #48-Ubuntu SMP Fri Jul 29 19:02:55 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux This is what I found in my xorg.0.log: [ 1873.079] [mi] EQ overflowing.
