I have a 7800 GS OC, and while 'dri' seems to work fine on it with nvidia's
nvidia-drivers, I haven't been able to get 'glx' to work.
If you have 'glx' working under linux with this card I'd like to hear about it,
and get the details from you that have got it working.
The thread below will show my system details, and other details that the nvidia
guys requested to find a solution... with no joy.
I guess they ran out of ideas.
Thanks for any suggestions.
