Description:
When resuming from suspend, I am left with a frozen lightdm login screen, neither mouse nor keyboard works. I do the only thing I can: I switch to another TTY, login and find the Xorg PID so I can kill it. Killing the process causes the TTY to switch immediately to TTY 7, where lightdm is now working and I can see that the system was able to keep my session intact.

So, the workaround is to kill Xorg every time I resume from suspend.

Additional info:
* xorg-server: 1.20.5-1
* lightdm: 1:1.30.0-2

Steps to reproduce:
- Suspend the system
- Wake it up

See log files attached.

System specs:
- Graphics: AMD RX 560 4GB
- Intel Core i3-8100
- Xfce4 as Desktop Environment
- Using lightdm as display manager, with lightdm-gtk-greeter and light-locker to lock screen.
