OpenGL Gentoo...

WingsofGOD · Oct 18, 2005

Is there something special you have to do in Gentoo to make the gfx drivers work properly? I did the usual downloading from nvidia and installing them manually. My gaming sucks, more like im on a mmx440 than a 6600GT

Tried using the emerge nvidia-kernel and nvidia-glx... wouldn't even start X that way. Complained about not finding the driver.. Ran Modules-update and i could then modprobe it to load. X still said it couldnt find it.

Whats the trick...

From what you have said it sounds like you have but have you checked over the instructions here: http://www.gentoo.org/doc/en/nvidia-guide.xml ?

Post the errors that you get when you emerge nvidia-glx and nvidia-kernel.

WingsofGOD · Oct 18, 2005

There where no error's when emerging the modules...

But i did manage to figgure it out. Hadn't yet rebooted to the new kernel i had compiled, and it was screwing with nvidia...

I am thinking that the lack luster performance using the nvidia installer was due to it using xorg's libgl libraries instead of the nvidia libgl's....

While we're at it, why does emerge install a really old version of the nvidia drivers 1.0-6629 ?

Because you are set to the stable branch apparently. If you want the more recent drivers, use the ~x86 keyword.

What do you get when you run glxgears (fps)?

I just noticed some REALLY weird behavior. glxgears seems to get around 7200 fps on my 5900. However, if I background the app by clicking on other windows so it's not visible, the fps shoots up to over 13000. Why is that? Same thing happens on my 6600.

Yeah, the nvidia module compiles against whatever is in /usr/src/linux, so the module will only work with that kernel version. If it's different than the one you're running, it won't load.

Don't know. With the drivers in portage, you can switch between the two and check the performance difference (using opengl-update or eselect opengl).

While we're at it, why does emerge install a really old version of the nvidia drivers 1.0-6629 ?

Yes, but you can:

Code:

echo "media-video/nvidia-kernel ~x86" >> /etc/portage/package.keywords
echo "media-video/nvidia-glx ~x86" >> /etc/portage/package.keywords

to have portage grab the latest version instead.

also make sure you've done,

Code:

eselect opengl set nvidia

It always does that, I guess because it does not actually have to show you drawing them when you can't see it.

Since the window is not visible, it doesn't actually have to draw anything, which makes it much faster.

I appreciate everyones help on this issue. Thanks to all the input it has been resolved. Running smooth as silk now.
