Public bug reported:
On Ubuntu 12.10, updates applied - top shows compiz using between 300
and 500% CPU (it is an 8 core AMD processor), and the system runs slower
than it should. 8GB RAM. It is a fairly recent nvidia card (default
nouveau drivers). lspci shows "NVIDIA Corporation Device 0fc6 (rev a1)"
$ lsb_release -rd
Description: Ubuntu 12.10
Release: 12.10
$ apt-cache policy compiz
compiz:
Installed: 1:0.9.8.4-0ubuntu2
I don't care much about the desktop, I work on the kernel - but I really would
like to have compiz not use most of the CPU on the system.
How do I fix or turn off compiz?
