<pre>Reproducable 100% of time.
I quit Sagara Family from main menu and monitor loses signal instead of showing
desktop. I can restore signal by lowering resolution with ARandR and then
putting 1920x1080 back.
journalctl shows this:
com.deepin.daemon.Display[6672]: manager.go:575: [updateMonitor] Set mode '115'
failed: Invalid output mode: 115

------------------
Arch Linux stock kernel does above mentioned behaviour. Linux
4.12.0-1-amd-staging loses signal from second monitor instead of first one as
soon as game is launched, and signal can be restored the same way.</pre>
