Default OpenGL running real slowly (glxgears <= 10 fps)

Hi all,

I'm using Gentoo and have always had no problems getting my nvidia card running smoothly, but sometime recently my OpenGL performance has died. glxgears reports less than 10 frames-per-second.

Anyone have any ideas? I'll attach the nvidia-bug-report-sh output.

Thanks!
Paul

1.0-9755 is no longer supported. If this problem persists after installing 100.14.11, please attach the output from glxinfo.

ThinkTiM, what is the output of "eselect opengl list"?

Most likely you just need to run "eselect opengl nvidia" if you installed from ebuilds, and/or reinstall the driver if you installed with the official package.

[edit: you'll have better results if you do this as root]

Try adding your user to the 'video' group.
Might help since the Gentoo maintainers
changed permissions on /dev/nvidia*
from 666 to 660 recently.

see http://bugs.gentoo.org/show_bug.cgi?id=183567

Thanks to everyone so far. Unfortunately I already have myself as a member of "video" and had tried the eselect to no avail.

I upgraded to the latest driver (it's masked in Gentoo's portage) and the OpenGL part now works.

But now my problem is that I absolutely cannot get the resolution to go above 1280x1024 - my LCD's native resolution is 1600x1200. Is there a bug in the new driver?

There are no known bugs which would prevent 1600x1200. See the forum sticky posts.
