Hi I was doing some experimenting and it turns out the 2d accel from nouveau is far better than the proprietary driver's. Shame it doesn't have any 3d though. Is this normal?

Exitium · 2010-02-08 21:15:43

nouveau does not support 3d acceleration, so it's normal

Ok but is it normal for 2d to be better on these drivers than the proprietary drivers?

tavianator · 2010-02-08 22:33:35

Depends on the chipset. Some say it's better, some say it's worse. And if you have an nv50 generation card, there is enough 3d support to run compiz; you just need nouveau-dri-git from the AUR. But it's extremely unstable and I've gotten a couple lockups with it, so be warned. YMMV.

You can try the 3D without installing it system-wide with

LIBGL_DRIVERS_PATH=/path/to/nouveau-dri-git/pkg/usr/lib/xorg/modules/dri glxgears

I have an nvidia Geforce FX Go5200 which I think is fairly old. I was just experimenting because my 2d accel is pretty bad with the official drivers.

Are you sure you installed the right official drivers ? You need the 173xx drivers for your card.

bananaoomarang · 2010-02-09 16:35:32

Yeah I have got them but 2d accel is about 2 times better with nouveau and nv. I have them from nvidias site but have tried them installed by arch. It makes no difference.

Can you paste the output of "nvclock -i" ?

by the way I am now running arch repo drivers

I enabled fastwrites now but 2d is still boringly slow. Well maybe 2d is just better with nv and nouveau.

Maybe your gpu clock is faster when using nv/nouveau (200mhz) than nvidia if it's running at the lowest level (100mhz) ?

bananaoomarang · 2010-02-11 08:10:47

How would I change that?

bananaoomarang · 2010-02-15 15:05:29

Well I can't compile nouveau-dri-git without installing a bunch of other cutting edge git packeges first so can't try out Gallium 3d. It is sort of usable now judgeing by this

but when I tried to install the rest of the dependencies it wanted to remove most of kde so I didn't go ahead.

That's not possible.

bananaoomarang · 2010-02-15 18:40:27

I thought not but it did try. However I was using yaourt because of having so many dependencies. It said it was conflicting with the kdemod packages but I can't remember specificaly which ones. I never have been too impressed with yaourt though. Maybe I will try and do some manual building. Arghh dependency hell.

##/etc/modprobe.d/modprobe.conf

options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"

you can add this to stop the proprietary nvidia driver from lowering the clock speed - there are ways to do it without fully disabling the scaling, but it has never worked for me
