hopefully this is a real easy one - i use lxqt which comes with sddm as standard but i cannot stand xscreensaver (something out of the 80's), so i thought i'd change the DM to lightDM (with lightdm-dinit) and use light-locker instead. All went as expected, but when going into standby, then coming out, i get a double login screen then a blank screen, no tty2, just frozen. I'm guessing I'm missing something obvious, but have drawn a blank. Any ideas?
Light locker can indeed cause problems with LXQT and Lightdm.
Iirc I removed it, and changed the end of file ~/.config/lxqt/lxqt.conf to:
[Screensaver]
lock_command=dm-tool lock
I'm not sure if I made any other changes; later I had to drop lightdm to run Xorg without root.
