+Subject: data: add back check for gnome-shell before running gdm-shell session
+
+Add back commit 4892c9447324f2248ce944f150abe3143f78eaa3
+
+This commit does a quick check to make sure gnome-shell is
+installed, and supports --gdm-mode. If either of those fail,
+then fall back to the old greeter.
