Re: [gentoo-user] Nvidia GeForce GTX 960

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.

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"
