XFCE LightDM lock issue

Hello!

I have recently switched to XFCE and installed LightDM as my display manager. I have then chosen a greeter (at first webkit2) and installed light-locker to enable locking the screen. This last feature however does not work correctly. After unlocking the screen the resolution of the greeter is wrong (certainly not the one I am using nor the one used after boot) and after inserting the password and logging in the screen goes black and never enters the DE. I need to switch tty and restart LightDM in order to fix it (but then my session is lost).

I tried changing the locker and the greeter, but the problem occurs regardless. I also found out that locking the screen or even switching to the greeter using dm-tools results in same behavior.

I can provide any log file you need, but please tell me which to send - I have no idea which od them would be of any use.

Re: XFCE LightDM lock issue

The lightdm log and the greeter log in /var/log/lightdm would be a good place to start.

Re: XFCE LightDM lock issue

I have a similar issue.  Upon locking, my screen resolution goes to 4K instead of the preferred 1080p.  Do you have a display setup script in your lightdm.conf?  Also, do you have hybrid graphics?

Re: XFCE LightDM lock issue

Well, I turned out uninstalling XFCE and switching to Cinnamon, which solved the problem, therefore I can't send you my configuration script. However I was using a desktop PC.
