We’re having trouble with VNC remote administration hanging or freezing all the time. When someone logs out or disconnects from VNC. systemctl restart displaymanager vncmanager usually fixes it. I would like to do this on every logout. I tried using /etc/gdm/PostSession but it isn’t working. Any ideas how I could do this? systemd service?
I use KDM3 from repo http://download.opensuse.org/repositories/KDE:/KDE3/15.4/ as default-displaymanager. I have it configured via kdmrc to restart on every session exit. I’ve never used GDM, so have no idea what it’s capabilities are.
I would expect Ctrl-Alt-BS or Ctrl-Alt-BS twice quickly should have the same effect from the GDM login screen, but Ctrl-Alt-BS might need to be enabled via /etc/X11/xorg.conf.d/.
