I am using Xubuntu 11.04 with the default nouveau driver for nVidia Corporation NV17 [GeForce4 MX 420] graphics controller. Xorg takes all available CPU power, if I run Update Manager in this system; it happens when Update Manager shows progress bar before you can Check or Install updates. Same thing happens, if I run pavucontrol that shows a volume meter moving along with to sound playback volume. I can see high xorg load in another computer that has Intel graphics, but it does not take that long time. Is this a bug in nouveau driver?
