Trying to get a dual GPU laptop to work right - GLX-related errors

My goal: run video games on the laptop using NVidia's GPU. Intel GPU doesn't matter, can be disabled/left unused if possible.

This is where I'm currently at: glxinfo and optirun glxinfo return "Error: couldn't find RGB GLX visual or fbconfig", while glxgears and optirun glxgears return "Error: couldn't get an RGB, Double-buffered visual". Also, when trying to launch an OpenGL game (eg. Minecraft), I'm getting the "Could not init GLX" error, regardless of whether I'm using optirun or not. Similar errors in Xorg.0.log

What have I done?:

  • installed kernel 4.16
  • ran sudo mhwd -a pci nonfree 0300 in order to install proprietary drivers
  • followed the "Using nvidia" steps on Arch Wiki: (placing these "Section" lines in /etc/X11/xorg.conf.d/90-mhwd.conf didn't help)
  • attempted to reinstall libgl with sudo pacman -S libgl

but no dice.


What have I done wrong?
Oh, I forgot to mention, it's a GTX 960M.

mhwd -li
(note - most likely you have doubled down by adding those extra lines to mhwd - it sets it up for you)
Oh, and also always a good place to start:
inxi -Fxzc0

(EE) Screen 1 deleted because of no matching config section.
(II) UnloadModule: "nvidia"
(II) UnloadSubModule: "wfb"
(II) UnloadSubModule: "fb"

And then

(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

You need a "matching config section." for nvidia . You said you edited xorg.conf file.
What exactly, which file?
Post it here please.
Can your system (which is?? give us inxi -SGxxz) disable intel GPU from BIOS? Do it if it is possible, as you say you don't need it.
Else you should use modesetting as described in the wiki you gave.

I dont think so. I think they should be using bumblebee, should not have done what the wiki outlines instead of what mhwd provided, and then should add to /etc/X11/mhwd.d/intel.conf :

Section "OutputClass"
    Identifier "intel"
    ModulePath "/usr/lib/xorg/modules/extensions"

Or thereabouts, but more info would be helpful.

I have edited it exactly as the Arch Wiki describes, while remembering to replace the Bus ID of course. However, I didn't make changes into the xorg.conf file, instead I did changes in xorg.conf.d/90-mhwd.conf.

While I'm not here, a person with a nickname of 'psvarek' will provide you with more info of that laptop :slight_smile:

Here you have what I’ve got from mhwd -li :

[arek@arek-pc ~]$ mhwd -li

> Installed PCI configs:

NAME                                VERSION             FREEDRIVER    TYPE

Warning: No installed USB configs!

And here is what I got from inxi -Fxzc0 :

Here you have content of this ( /etc/X11/xorg.conf.d/90-mhwd.conf ) file.

And I was looking in BIOS options and there wasn't any that could allow me to disable intel GPU.

There is a very detailed and complete Tutorial for this issue.
Please read it carefully and follow it. If your issue is not solved report here for any more assistance.

Edit: please use code blocks for your provided outputs. Be kind and apply that in your posts.

We have rolled back our changes and followed the guide, now desktop never appears and instead the monitor keeps blinking repeatedly (as if it was changing resolutions over and over) while showing black screen. Sometimes the login screen appears for a split second before disappearing again.
We'll try to get the Xorg.0.log file by booting from USB and we'll post it here.
