I am also experiencing this. Total lock up, nothing moves.. It seems to happen most frequently in Firefox when making a mouse click, either right, left or scroll. It doesn't happen if I don't touch the system.
The only way out is a system reset button. Then Ubuntu does a disk check, most often than not automatic fsck fails and I get sent to the console. Typing a fsck will fix the problems. Then you have to reboot. This is TOTALLY unacceptable to a normal user. To make matters worse, today I got a message saying that GDM could not be started. Again another reset to get the system back. Guys, this has to be of a VERY HIGH priority!!!!! Its getting to remind me of the good old windows blue screen days....
