[Bug 1899638] [NEW] ubuntu-bug won't show GUI window in pure wayland-sessions

Tue Oct 13 13:27:48 UTC 2020

Public bug reported:

In case only `WAYLAND_DISPLAY` env variable is set (but no `DISPLAY` as
XWayland is disabled), ubuntu-bug won't show its window, even though GTK
will use the Wayland backend.

Test case, in an Ubuntu wayland session:
 - Run:
      env -u DISPLAY ubuntu-bug -w apport

You will get:

So, ubuntu-bug should both consider `DISPLAY` and `WAYLAND_DISPLAY` to
be enough to use a graphical session.
