I upgraded my Asus Eeepc 900a to 10.4 yesterday. Since then, Xorg has averaged between 30-40% CPU, and my fans have gone nuts running high/low/high/low, ad nausium.
Any ideas what might be going on? Another clue perhaps: on reboot or shutdown, I get a "program not responding" message with "unknown" as the hung program. I have not been able to determine what this program is or if it is related to the hyperactive Xorg.
