Hi Silvio, I think the problem is that you have told portage to use both nouveau and nvidia as a driver for your card. If you have both drivers installed and do not blacklist one of them, the other will not work.
> # modprobe nvidia > modprobe: ERROR: could not insert 'nvidia': No such device If nouveau takes control of the card first, for example, you will not be able to load the nvidia module anymore, just as it happens to you here. > # lspci | grep VGA > 01:00.0 VGA compatible controller: NVIDIA Corporation GM206 [GeForce GTX 960] > (rev a1) You can run 'lspci -k' to see which driver is in use for a PCI device. This will probably return 'nouveau' for you. You can also check lsmod for the 'nouveau' module. > # cat /etc/portage/make.conf | grep VIDEO > VIDEO_CARDS="nouveau nvidia" I'm assuming you want the proprietary driver, so change this to read the following and run 'emerge -c' to get rid of the superfluous driver: VIDEO_CARDS="nvidia" -- Wolf
