Optimus Manager Trouble

Support Graphics & Display
1

I hit a wall when trying to make optimus manager to work, when I try to run optimus-manager I get the following error. I’m attempting to use the proprietary driver.

ERROR: a GPU setup was initiated but Xorg post-start hook did not run.

If your login manager is GDM, make sure to follow those instructions:
GitHub - Askannz/optimus-manager: A Linux program to handle GPU switching on Optimus laptops.
If your display manager is neither GDM, SDDM nor LightDM, or if you don’t use one, read the wiki:
FAQ, common issues, troubleshooting · Askannz/optimus-manager Wiki · GitHub

Cannot execute command because of previous errors.

This is the log the error refers:

I have the same problem with slightly different log output:

I followed these instructions when setting up optimus-manager: Guide: Install and configure optimus-manager for hybrid GPU setups (Intel/NVIDIA) - Tutorials - Manjaro Linux Forum

It has worked fine before, but for reasons unknown to me it just stopped working. After the last major Manjaro stable update of Dec 30 2020 I uninstalled and reinstalled optimus-manager following the aforementioned guide, but to no avail.

Looks like there’s a fix (for GDM at least): Can't switch due to Key Error, and manager in inconsistent state · Issue #350 · Askannz/optimus-manager · GitHub

I’m not sure when the fix will be rolled out though

I have been unable to switch between Intel and Nvidia drivers as when I try to switch to Nvidia driver using the terminal command “Optimus-manager --switch Nvidia” it shows the following error
"ERROR: the latest GPU setup attempt failed at Xorg pre-start hook.
Log at /var/log/optimus-manager/switch/switch-20210205T122415.log
Config parsing : error in option “dri” in section [intel] : invalid value “0”
Config parsing : unknown section [amd]. Ignoring.

Cannot execute command because of previous errors."
please help

These indicate problems with the configuration. Please check if you have a valid configuration file.

same in my gnome

the instructions on how to fix it foresee such an error … but why following the instructions cannot fix it …on XFCE working normal
