It is not possible to switch without rebooting, so the correct procedure would be: CORRECT PROCES TO FOLLOW to switch between nvidia and noveau. (assuming the kernel is using nvidia) to switch to noveau: mv /etc/modprobe.d/blacklist.conf_nvidia /etc/modprobe.d/blacklist.conf eselect opengl set xorg-x11 mv /etc/X11/xorg.conf_nouveau /etc/X11/xorg.conf reboot Assuming: cat blacklist.conf_nouveau blacklist nouveau cat blacklist.conf_nvidia blacklist nvidia cat xorg.conf_nouveau # uncomment when the card gets IN Section Device Identifier nouveau Driver nouveau EndSection at xorg.conf_nvidia Section Device Identifier Nvidia card Driver nvidia EndSection -- Joseph
