Default Re: Amazon EC2 PBuffer FBO rendering dual Tesla xconfig EE /dev/fb0

Wow, I cannot believe that this was the problem. I started from a plain Ubuntu 11.04 and installed the NVIDIA driver on that. I donīt know why there was an X86FConfig file in /etc/X11 there and why nvidia-xconfig changes that file instead of the xorg.conf. Well, deleting the X86FConfig and rerunning
sudo nvidia-xconfig -a --use-display-device=None --virtual=1280x1024
solved the whole problem and I could run X with OpenGL support to perform offscreen rendering.
This is great. AaronP I owe you a pint!
