Hi - had problems getting nouveau to install, recent updates through ubuntu
intrepid repository (ppa) to 1:0.0.0~git20081009-0~ppa1


Have problems with high cpu use using nouveau particularly when changing
desktops, using fluxbox as window manager. Seems to use a lot of memory at
start - free -m buffers up from ~120MB to ~650Mb on start. Only difference
being the nouveau driver.

Have tried to use oprofile to get data - not sure if it's right or even if it
helps.

Graphics card - Nvidia Geforce4MX440

Unfortunately, there's nothing useful within the oprofile output. If you're
serious about trying to track down the cause of CPU usage, I would suggest
trying to see if one of the X apps can result in a CPU usage spike. Even
better, if you have a small program to show a problem.

For example, if you have some benchmarks over a series of time that show the
driver operating worse after a particular version. That would allow the
maintainers to revert whatever change caused increased CPU + mem use.

If you get something more concrete, feel free to open a new bug.
