I have a strange problem with my Fedora-14 system. If I play an avi file, the keyboard locks up and mouse clicks are ignored. This also happens once in a while during web browsing.
As a result, I can't do anything with the computer till I do a hard reboot. The strange thing is that in the locked up state the mouse pointer moves -- so the system is not dead!
My hardware is pretty standard with an Intel mother board and USB keyboard/mouse. I can dig out the mother board number if required. The Fedora 14 set up was updated till the updates stopped. Moving to a Gnome 3 based distribution is not an option, even with this annoyance in Fedora 14!
