Installed deepin, and desktop goes to black empty screen with mouse

I wanted to try Deepin desktop, so I ran sudo pacman -Syu deepin. When I rebooted and selected Deepin on the login screen (gear cog in GDM), then logged in, it took me to a black empty screen with nothing but the mouse.

It's been a while. How can I start this from another VT so that I can see console output?

I figured how to stop gdm from a VT, with systemctl stop gdm.service, but then when I try to run startdde I get an error:

$ startdde
startdde[674]: main.go:39: empty display string

$

When GDM was running, I was able to run DISPLAY=:1 startdde and avoided that error, but then it had other problems (I think because GDM is already running there).

If I try running startdde in Gnome, I get some errors, but the Deepin mouse theme then overrides the Gnome mouse theme while I'm in Gnome.

Any ideas?

Deepin is currently not supported on Manjaro.
