 |
|
First post here!
I'm currently running Gentoo on my laptop and currently only using the laptop display.
`lspci -k | grep -i vga -A3`
| Code: | 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
Subsystem: Lenovo 3rd Gen Core processor Graphics Controller
Kernel driver in use: i915
--
01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GTX 660M] (rev a1)
Subsystem: Lenovo GK107M [GeForce GTX 660M]
Kernel driver in use: nvidia
Kernel modules: nvidia_drm, nvidia
|
I've installed `x11-drivers/nvidia-drivers` and I've also downloaded and installed the driver from NVIDIA's website (version 418.113 per their site).
I generated my xorg.conf file via `nvidia-xconfig`. It looks like this:
| Code: | # nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 418.113

If I run `startx` with just `exec i3` in my `.xinitrc`, I see the following errors in `/var/log/Xorg.0.log`:

And while I'm able to start X windows, I see a new issue, and I fear X is not utilizing my NVIDIA card. It's not able to load `glxservernvidia`, but I have `/usr/lib64/xorg/modules/extensions/libglxserver_nvidia.so` (note underscore).

Is it an OPTIMUS laptop ? I have a feeling that NVIDIA in optimus setup is not directly connected to the screen, intel controller is.
