Nvidia GF 960M - struggling with drivers for X on Optimus enabled laptop

**kalimera** · 2016-12-30

Hi All,

Looking for your assistance as I’m getting clueless on how to get running X on Nvidia drivers.
The hardware is Lenovo Y50-70 with Intel and Nvidia GeForce 960M.

Code:

00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2)

As per above, switchable graphic is enabled in bios. There’s option for Nvidia GPS (GPU Performance Scaling).

I’ve followed almost any recommendation on the web (and I’m sure I’ve missed the right one), but couldn’t get the system working.
I’ve properly disabled nouveau, have X starting on Intel (confirmed with running X directly). With current layout I can’t get GDM3 login window and I’m being presented with white screen that something went wrong.
Troubleshooting and log review confirmed that this is due to missing GLX support.

I’ve tried multiple settings and I’m missing the right one.
Understanding of the problem is that Intel (i915 driver?) is responsible for VGA interface and display leaving Nvidia in the background for 3D/GLX.

Starting X from console and from other console (via ssh):

running

Code:

# DISPLAY=:0 xterm

works and displays xterm window.

Code:

# DISPLAY=:0 optirun nvidia-settings

On the console:
Xlib: extension "GLX" missing on display ":0".

Code:

And within X, claims that system doesn’t seem to be using Nvidia driver.

running DISPLAY=:0 option xterm

Code:

kernel started with (tried with different settings with same results as above:

EndSection

The most far I’ve went was by following one of guides (can’t find link):

Code:

# /etc/X11/xorg.conf
Section "ServerLayout"
    Identifier "layout"
    Screen 0 "nvidia"
    Inactive "intel"
EndSection

Section "Device"
    Identifier "intel"
    Driver "intel"
    BusID "PCI:0@0:2:0"
    Option "AccelMethod" "SNA"
EndSection

Section "Screen"
    Identifier "intel"
    Device "intel"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1@0:0:0"
    Option "ConstrainCursor" "off"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

This was giving me (note bumblebee is disabled):

Code:

# DISPLAY=:0 glxgears


Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
182631 frames in 5.0 seconds = 36526.180 FPS
183675 frames in 5.0 seconds = 36734.848 FPS

btw. values seem to me really high, probably way too high.

TBC in next post.
