Arch Linux

Description:

I am able to log in like normal on boot, through the lightdm-slick-greeter. But if I manually lock my screen (not sleep) and then try to wake it again, it's just black, with my spinning cursor on top. Then it goes back to being entirely black after a few seconds, until I wake it again and get the same result.


Additional info:
* package version(s)
lightdm 1:1.32.0-4
lightdm-slick-greeter 1.6.0-1
eos-lightdm-slick-theme 3.2-1
xfce4-screensaver 4.16.0-1

* config and/or log files etc.

This is an excerpt from journalctl. There's a longer excerpt in the attached file.

Looking for that now
