Is there some way that I can have Xinerama enabled and still use hardware acceleration? I have three monitors on 2 GPUs. I have enabled Xinerama, but now all hardware acceleration is gone. This results in bad framerates in games, and Compiz isn't working properly. In case this is impossible, is there some way to move applications between X screens without Xinerama? Here is my xorg.conf, generated by NVIDIA X Server Settings:
