Podman loses access to my GPU when I log out (self.linuxquestions)

I have lingering setup and I can still access the container but for what ever reason Podman seems to be unable to access the GPU for no apparent reason.

I think this may be an issue with systemd but I'm not entirely sure.

Solution: you need to be logged in for it to work. I accomplished this on a separate VM with autologin to icewm.

Interesting. For me, it's only the /dev/dri/render* device that is owned by the render group, but this device is world-RW anyway. Still, I guess you can add the user to the render group too? I did find some info that Debian uses that group this way, though I have never used Debian myself, so can't verify that.

I already did that so that podman could access the device. (Podman runs as a local user). What was strange was that podman couldn't access it without a graphical session running but my local user could.

No idea then :( AFAIK the logind mechanism I mentioned originally is based only on permissions, but I had never really needed to look into it further.
