[SOLVED] Picom fails to start, but works after switching TTYs

I'm trying to start Picom with 

$ picom

but receive the following error:

[ 09/08/2021 22:30:07.245 vsync_init ERROR ] No supported vsync method found for this backend
[ 09/08/2021 22:30:07.245 session_init FATAL ERROR ] Failed to initialize the backend

Trying '$picom --diagnostic' '$ picom --backend xrender' also produces that error. 'glx' and 'xr_glx_hybrid' backends instead produce the error:

[ 09/08/2021 22:36:39.369 vsync_opengl_swc_init ERROR ] Failed to load a swap control extension.
[ 09/08/2021 22:36:39.369 session_init FATAL ERROR ] Failed to initialize the backend

However, if I log out of and log back in via LightDM (regardless of which session I select), or switch to any other TTY with 'alt+ctrl+f<n>' (after entering credentials and entering 'startx'), picom starts fine without any error messages.

My graphics card is a GeForce GTX 1060 3GB. I do have an internal graphics card but nothing is connected to it, and I'm not trying to use Nvidia Optimus. Here's the full output of lscpi

This is what entering 'glxinfo -B' looks like:

My first guess is that the driver was being loaded after startup, so I've tried adding 'nvidia, nvidia_modeset, nvidia_uvm and nvidia_drm' to the MODULES array in /etc/mkinitcpio.conf, as well as adding the 'nvidia-drm.modeset=1' kernel parameter to '/etc/default/grub' and generating the config file (to be completely honest I don't know if nvidia-drm.modeset=1 was necessary). After performing those steps, the issue was not resolved.

I'm running LightDM and i3 together, and no desktop environment. I've tried running ~/.xinitrc as a session, but that didn't seem to have any effect.

I've tried various boot configurations for the sake of seeking what sticks but as of now I'm not sure after several hours of troubleshooting. How can I get picom working (or rather, how can I get the nvidia drivers to load) after initially booting up? I would really appreciate the help. Below I have copied and pasted package versions, Xorg & LightDM log and related configuration files.

Package versions:
- lightdm 1:1.30.0-4
- nvidia 470.63.01-5
- picom 8.2-1
- And also: 'Kernel: Linux 5.14.1-arch1-1'

Edit:

# The above line seems to work okay. If I omitted it, the screen would be black after logging in

https://wiki.archlinux.org/title/Displa … _a_session

I do have an internal graphics card but nothing is connected to it

It's not in lspci either…

My /etc/X11/xorg.conf

nvidia-settings generated garbage, please move that away.

I'm not trying to use Nvidia Optimus

In doubt: https://wiki.archlinux.org/title/NVIDIA … phics_only (but it looks like you deactivated the IGP - some boards do thta implicitly when there's a dGPU - in which case that's not relevant)

Re: [SOLVED] Picom fails to start, but works after switching TTYs

Issue solved. Thanks for the help Seth. I was wrong in trying to avoid using Nvidia Optimus but my misconceptions were corrected after a deep dive of research.

I followed these instructions here: https://wiki.archlinux.org/title/NVIDIA … de_setting, here https://wiki.archlinux.org/title/Kernel … _KMS_start, and here https://wiki.archlinux.org/title/NVIDIA … phics_only, in that order.

It should also be noted I also cleaned up my LightDM configuration (lightdm.conf) file. I had set configurations in the section of the file where there was comments with examples, and thus my display_setup.sh script was not being executed (which is important to have executed if you try follow the last link / try to use Nvidia graphics only). After putting display_setup.sh below the [Seat:*] section (the correct spot), I restarted the x server with 'sudo systemctl restart lightdm' and everything worked out from there. Hope this helps someone.
