Bug#895676: gnome-session: Black screen only when choose "GNOME on Xorg" session

[Kamen Naydenov]

Package: gnome-session
Version: 3.28.0-2
Severity: normal

Dear Maintainer,

   * What led up to the situation?
On GDM greeter I choose "GNOME on Xorg" session.
Then I login.

   * What was the outcome of this action?
After login there is only black screen instead of gnome-shell. After a while I
was presented with GDM greeter again.

   * What outcome did you expect instead?
I expect to have a normal gnome-shell experience.
