Re: [TurboVNC-Users] Ubuntu 22.04: Issues with VNC session if physical session is logged out

['DRC' via TurboVNC User Discussion/Support]

I will check the diffs when I am in front of my computer, but I performed the same experiment and didn’t see anything in the environment that might explain the problem except for XAUTHORITY. I am also testing with a VM, incidentally, using VMWare Fusion on my Mac, since my physical Linux machines run RHEL derivatives.

Can you tell something other than $XAUTHORITY? Many Thanks and Best Regards! Felix Felix Natter schrieb am Samstag, 20.

This would also explain why you don't see the problem with lightdm.  lightdm sets XAUTHORITY to ~/.Xauthority, which is the traditional X authority location that doesn't rely upon systemd. -- You received this message because you are subscribed to the Google Groups "TurboVNC User Discussion/Support" group.
