Re: why My X usually up to 20-40 % of CPU usage? How to settle this?

It's probably due to intel being crippled at the moment, until the GEM-enabled kernel gets released/hits the repos (that would be .28).

Downgrade Xorg or bite the bullet until the kernel arrives.

I made update, after that my system goes down. Xserver don`t want to start.
Then I made downgrade to xorg 1.4, but now stable 15% of CPU usage take xorg. I`m waiting new kernel...
