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. |

Created attachment 19552 [details] oprofile text 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
