hello. i'm running a geforce 6600 (twinview, two dvi monitors) alongside a geforce 5200 (one dvi monitor).

i can get opengl working fine with either card on their own but not with both active at the same time (xinerama).

glxinfo gives the following:
there are no (WW) or (EE) in /var/log/Xorg.0.log

i'm running fedora core 6 (didn't put this in that forum because i shouldn't think this is due to the distro i'm using). rpm -q kmod-nvidia shows kmod-nvidia-1.0.9746-1.2.6.19_1.2895.fc6 -- this is the latest version of the nvidia driver as far as i'm aware.

i'm not expecting to be able to get opengl spannable across all three screens, but i'd at least like to be able to use opengl on the middle screen (or, since the middle and right are twinview, those two at the same time).

running glxgears gives similar errors (the same but with 18 as the last number instead of 14), and i get similar errors whenever the machine tries to use opengl (for instance if i click to go to the "opengl/glx infromation" page of nvidia-settings it crashes with similar errors in the terminal, or when trying to load quake3).

in case it helps, my current xorg.conf is at http -- rafb.net/p/K29j3C48.html (since it's my first post i'm not allowed to post a url!)

any ideas on how i can get this working?

thanks a lot

The latest nvidia drivers are not always the greatest when it comes to older cards. Drop back to the nvidia version 9626 and see if that resolves your glx problem. It did on my ti500.

thanks for the suggestion. the only older driver held by livna is kmod-nvidia-96xx-1.0.9631-4.2.6.19_1.2895.fc6 and i've just replaced the latest with it and restarted. unfortunately, there's no change.

i hadn't actually realised until earlier today, but i also get the same errors when trying to watch video files. i can't be the only one running a tri screen setup with two nvidia cards...

i find it bizarre that watching video files was fine with one ati and one nvidia card together and now not with two nvidia. there's got to be a way to get this working.

any other ideas?

"any other ideas?"

Yup, uninstall the livna driver and get the driver directly from nvidia. Here's a link to 9626. You'll need the kernel-header package and possibly some other stuff before you can run the file. It will compile a new driver and install it.
