I'm having some difficulty with Steam. I installed the proprietary driver using Additional Drivers, and up until now, thought it had installed correctly. All my desktop effects worked flawlessly.
But, when I tried to run steam, it said,
"OpenGL GLX context is not using direct rendering, which may cause performance problems".
So, I thought that perhaps I hadn't installed the driver yet. Opening Additional drivers, it shows Nvidia 3.10, but says that
"This driver has been actived, but is not in use" Trying to launch Portal, is says it couldn't find the
"required entry point 'gelGetError'".
So, as far as I can tell, Steam thinks that I don't have the propietary driver installed. But, when I open Nvida X Server settings, it clearly says I have driver 3.10.
Can anyone please tell me what's going?
EDIT: Sorry for taking so long to respond, as requested, here is the result of running "lsmod | grep nv"
