I am investigating updating to an NVIDIA binary driver for a GTX 860M card on Ubuntu 14.04 running KDE. I am following the directions at NVIDIA Binary Drivers HOWTO but my system is not cooperating with the directions there. First off, the "Additional Drivers" UI does not show any restricted drivers available. But if I try to troubleshoot to see what drivers are in use through the CLI with
ubuntu-drivers devices command, the command does not output anything. Specifically, when I run
ubuntu-drivers devices I would expect something like this:
vendor : NVIDIA Corporation modalias : pci:something here model : GTX 806M or something like that driver : xserver-xorg-video-nouveau - distro free builtin driver : whatever binary drivers nvidia has available here...
but instead what I get is:
root@hades:~# ubuntu-drivers devices root@hades:~#
If I do a
ubuntu-devices debug then I do get output from the command -- a page or two of data that I can not make any sense of, but does not include anything related to vga (although there is some wmi stuff in there).
I believe that I am running the nouveau driver as
xrandr --listproviders shows
Provider 0: id: 0x6b cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 8 associated providers: 1 name:Intel Provider 1: id: 0x3f cap: 0x4, Source Offload crtcs: 0 outputs: 0 associated providers: 1 name:nouveau
lspci | grep -i vga shows
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06) 01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 860M] (rev a1)
but I am not sure what drivers to use at this point. Any advice would be appreciated. Thanks.
