lightdm xfce4 black screen after login

[flobe]

After doing a system update a couple weeks ago, my Chromebook Acer 13" CB5-311 started logging in to a completely black screen. It seems to boot without any errors, gets to graphical login prompt, then once I enter my password the screen goes black (off) for a second, then black (backlit) with the mouse cursor visible and working indefinitely. Nothing's using CPU.

My journalctl from time of login shows lightdm being stopped for some reason.. any idea what's going on? The journalctl log from time of login:
