[Bug 437607] [NEW] xorg takes 100% cpu -- but only on first login

 

Public bug reported:

Binary package hint: xorg

On Ubuntu Karmic & Nvidia's non-free drivers: after logging in, Xorg
takes 100% CPU. No application seems to be redrawing anything (no
firefox. Xorg is also the only large CPU user). Apart from the large CPU
usage, everything seems to be working normally.

The curious thing is that the situation is fixed by logging out (back to
gdm), and then logging in again. Then, Xorg's CPU usage is back to
normal.
