Hey Heiko, I got that the first time, but I think that should be exactly the same thing. Unfortunately it seems that the greeter session doesn't have the same permissions through loginctl/systemd/udev stack, at least I don't have the acl either. I don't have much clue here but I don't think it's something specific to LightDM though. > > Hence without user "lightdm" being in group render, lightdm only displays > said black screen and the error in the seat-log and does _not_ reach any > login prompt at all. What greeter do you use? Here (with lightdm-gtk-greeter) even without the correct acl on /dev/dri/renderD128 I don't have permission access in the log, and obviously it works just fine for everyone else. I'm unsure if it's mali-related (I don't really see why) or more software related.
