Nvidia-settings and nvidia-smi hangs + other weird issues

My laptop has Nvidia 750M along with 4th gen integrated Intel graphics and is on Manjaro-KDE-minimal. I have video-hybrid-intel-nvidia-390xx-bumblebee installed. The problem that if I launch nvidia-settings from application launcher it just doesn’t open. If do it from terminal, I don’t even get any output. Same behaviour with nvidia-smi also.

As an after effect, shutdown or restart takes extremely long and displays Waiting for process: nvidia-settings, Xorg

Whats even weird is that this is not happen every-time! Roughly once every 20 reboots, everything just works fine. I can launch nvidia-settings and the shutdown/reboot is also smooth. Please help me with this. :pleading_face: :pray:

I am not very experienced with his but I still tried to poke around, try solutions and carry out an investigation to the best of my knowledge as detailed below:

  1. If I execute pgrep nvidia-settings to get pid to try to kill it with kill -9 pid , it just does not get killed!
  2. Adding noueau.modeset=0 to GRUB_CMDLINE_LINUX_DEFAULT=" " does nothing for me so reverted.
  3. I have tried ditching bumblebee and using optimus-manager but if I switch to nvidia with optimus-manager --switch nvidia , the screen goes blank after login screen.
  4. Tried running nvidia-settings -pm 1 at boot as a systemd service. This also did nothing for me but there is an interesting observation. If I check the status of the service I created, it mostly displays it was successful and nothing special. Remember I mentioned once every few reboots, everything just works fine. Whenever that happens, the service status is populated additionally with an output saying persistence mode is already enabled.
  5. If I comment out blacklist nvidia-drm from /lib/modprobe.d/bumblebee.conf the issue is resolved. Now, nvidia-settings and nvidia-smi works fine. But now some apps won’t launch. E.g, if I launch kitty , I get,
$ kitty                                                                                                                                                                                                                  
[286 13:33:58.376165] [glfw error 65542]: GLX: GLX extension not found
[286 13:33:58.376211] Failed to create GLFW temp window! This usually happens because of old/broken OpenGL drivers. kitty requires working OpenGL 3.3 drivers.

But if execute optirun kitty it just works!!

I am a student and want to get started with learning cuda. So, this is kinda necessary. The hardware is getting somewhat old and have started saving for a new device but this gets most of the job done and i think it is wiser to keep going as long as it can as the gpu prices get more reasonable.

At first, bumblebee/bbswitch is old and I think not maintained. It’s from times before render-offload existed.

Reading the optimus-manager docu from manjaro:

Supported display managers are : SDDM, LightDM, ~~GDM~~ . The program may still work with others but you have to configure them manually, see [ Using a different Display Manager](https://wiki.manjaro.org/index.php/Optimus_Manager#My_display_manager_is_not_SDDM.2C_LightDM_nor_SDDM).

You didn’t say what your display manager is, might be that…

Secondly, you also don’t say what your goal is regarding PRIME configuration.
If you want your nvidia gpu to render everything and the iGPU just to display it (like it looks from

), then this doc might help you understand better and do the right config manually (what optimus-manager is doing):
What it does (sadly) not cover, is adding the xrandr commands to the autostart scripts of your display manager.

Thirdly, if your goal is to run only certain programs on the nvidia gpu. In which case this doc about render-offload would be of interest:
