Bug Description

Since the moment when Ubuntu was upgraded from 11.10 to 12.04 GUI runs too slow for normal work.
Compiz consumes 21% CPU on idle and up to 90% on a window moving.

Anton,

I see you are using the fglrx driver. Does your video card support the radeon driver?

If you're not sure, then please try:
  1. Run: jockey-gtk
  2. Remove the ATI/AMD driver(s)
  3. Reboot

Then if you find that's no better, do this:
  1. Run: jockey-gtk
  2. Re-install the ATI/AMD driver.

Daniel,

Thanks. I've removed fglrx driver. You're probably right, CPU consuming
dropped to 0-3%. GUI runs much quicker, though it's still not perfect.
The strange thing is that fglrx driver worked in Ubuntu 11.10 without
such problems.

Thanks. I assume stant == astatutov ? :)

Yes, sorry, I've answered from the corporate email. :)
