upgrade from 10.04 to 10.10 100% cpu Xorg process

[aarons6]

my computer is unusable.. every time i click or open or move a window it freezes for several seconds. system monitor shows at this time the process Xorg is using 100% cpu.


it never drops down below 40%, even at idle.

my system is amd 64 4000+ 3gb ram and ati 3650 HD video.

i have kubuntu 64 10.10 with all the updates and default ati drivers.

How does 10.10 work when booted from a live CD?

Instead of running System Monitor, try the top command from terminal. (System Monitor itself uses up a lot of resources for graphs and all that).

And try to reconfigure your graphics by


sudo dpkg-reconfigure -phigh xserver-xorg

You mentioned default ATI drivers, I assume you mean the open source drivers. If thats the case, installing the proprietary drivers might help. System > Administration > Additional Drivers.

Good Luck!

nothing seemed to help, had to go back to 10.04

this does not use the ati drivers, so it runs normally.

Good, please mark the thread 'solved'.

Its not solved. 10.10 will not run on my PC.
I had to reformat and go back to 10.04.
