Comment 9 for bug 2052489

I had the same black screen after logging in to a virtual install in KVM from the iso file of Feb 5.
Moving to tty3 I ran startx and was surprised to see the GUI appear, though then running command
echo $XDG_DESKTOP_STYLE
I see output of tty, not x11 as I anticipated.
I normally remove all snap infrastructure from my installs without a problem, my machines all being fairly old and slow by modern comparison, but have not done so yet on this VM.
