Please provide howto/help for nvidia users
by Marc on Saturday 12/Jan/2008, @00:28

Please provide an official howto or something for kde4 users with nvidia cards - there should be a lot of them around. I read things like "do this" and "tweak that" to make accellerated effects smoother, but for me it just doesn't work.

I have the latest driver and a Geforce6600GT, and i read to this point:

- add "export KWIN_NVIDIA_HACK=1" to /etc/profile

- add
Option "AddARGBVisuals" "True"
Option "AddARGBGLXVisuals" "True"
Option "DynamicTwinView" "false"
Option "RenderAccel" "true"
Option "AllowGLXWithComposite" "true"
...to xorg.conf in section "Screen" and/or "Device"

- add / don't add
Section "Extensions"
Option "RENDER" "true"
Option "DAMAGE" "true"
Option "Composite" "Enable"
EndSection
...to xorg.conf

Without effects, all is smooth. With effects the Desktop Grid is smooth, but minimizing/maximizing, scaling in, moving and rotating of widgets and the overall impression is choppy.

Searching google and testing becomes really frustrating when you get no results, so pleease...

Hi there!
I have a GeForce Go 7200. For me kwin composite works very well - everything runs smooth and I had no crashes so far.
I'm using Debian unstable with the KDE4.0 packages from experimental.
Nvidia driver version: 169.07-1

My device section from xorg.conf:

Section "Device"
Identifier "GeForce Go 7200"
Driver "nvidia"
BusID "PCI:5:0:0"

Option "NoLogo" "1"
Option "RenderAccel" "1"
Option "AllowGLXWithComposite" "1"
Option "AddARGBGLXVisuals" "1"
EndSection

no other config files edited!

A HowTo for users with nVidia cads is most urgent. I have used a few tips here including yours for my xorg.conf file and KDE 4.0 is now as smooth as silk. I have 't been using KDE 3.5x since the release of 4.0.
The only problem that I am now having is with Firefox.

Concerning your xorg.conf file, openSuse Users should use the value "true" instead of "1" if they want to try your settings.

... smooth as silk with OpenGL-Effects enabled, especially minimizing and dragging around applets?

If so, please say what you did ;)

I tried that plus adjusted the xorg.conf file to that of Sepp (only using "true" instead of "1" on openSuse) and the effects are now really smooth. I am only having problems with Firefox, that the Plasma Panel flickers when I am writing like now.

Aaawww... i'm going nuts over this! I installed a clean new ubuntu, then KDE 4.0 with kdm-kde4, then the latest nvidia driver for the GF6600GT, configured xorg.conf and /etc/profiles...

and it's still totally jerky :-( Especially that others say it's totally smooth with them makes my head explode... i tried about everything, and minimizing or dragging things around is at best 5fps.

It's a shame, i just updated to this card to be able to enjoy kde4 with OpenGL, knowing it wouldn't be that optimised yet. I can play FarCry under linux, but it isn't good enough for kwin4??

ok, problem solved.

KDE4 's now running on top of compiz and emerald with a theme i copied from the kwin4-decoration. Looks nice and doesn't eat up my system.

I liked the look'n'feel of the more integrated kwin4 effects better, but not like that. If the kwin guys which i pointed to this thread will do some kind of comprehensive howto for nvidia cards, i'll be happy to test and bug report.

Hello,

I used the Xorg config from above, but with OpenGL the system is getting near 100% CPU load, only XRender works, which doesn't work with many effects, most notable desktop flip, which is sad.

So +1 to a how to.

Yours,
Kay
