For some reason the sysctl var is set to 3 even though I use Option "NvAGP" "1" in xorg.conf. Setting it manually before starting X leaves it at 1, but that doesn't help. > How did you compile the drivers?

I've tried commenting it out and I've tried leaving it on, but there is no difference in behaviour.home | help
