Hi all,
I'm not completely happy with my driver setup for an 8600M GT.
Using nvidia.ko, KDE with desktop effects enabled (especially translucent
popup thumbnails on the task bar, and blur effect on) makes my notebook fan
run all the time and kwin uses 20% cpu according to top. Oddly enough, the fan
runs faster with the screensaver on (displaying a single static jpeg) and
settles down when I unlock the screen.
Nouveau is supposed to be useable (if not entirely stable yet) but it makes
the fan run flat out, notebook gets hot very quickly, top reckons kwin is
using 30% cpu even with all fancy effects off and gui events have a noticeable
lag to them - a short but very noticeable delay after mouse clicks for
example. It all looks very much like some process is blocking as when things
get around to happening, they happen quickly - like glxgears spins it's wheels
at a terrific rate and very little gets in it's way once it starts.
I reckon it should not be this way and I have yet again done something stupid.
I've scoured the net and forums for howtos but found nothing and this has been
going on for at least 5 kernel versions.
Are there any known issues that cause things like this that I've overlooked? I
strongly suspect it's not an obscure detail peculiar to me, more like I
absolutely need kernel feature X for best results.

Does the blur effect do anything? With my ATI card, I did not notice a
change when enabling it, other than the CPU going really high.

Yes, it has a visible effect. It's subtle so you have to look closely but it's
there. The config popup for the effect has a slider for degree of effect but I
didn't see that change much, as if the range from min to max was not wide
enough

Happy news:
Upgrading to KDE-4.6.0 fixed all the annoying issues below.

Does this mean you are now running you nvidia graphics using the nouveau
driver? That is, not just testing nouveau, but using it essentially all
the time.
thanks,

No, I still use nvidia drivers for day to day work. I install and check out
nouveau every now and again.
Soryr. I should have re-read my mail and been more clear. The main issue I had
with nvidia was that desktop effects raised the load and made the laptop run
hot especially with blur effect. 4.6.0 fixed that and lets the machine perform
acceptably.
