Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. be logged into wayland session
2. open terminal
3. run gnome-system-log
No protocol specified
(logview:11210): Gtk-WARNING **: cannot open display: :1
that's because we don't allow root to access the user's Xwayland display.
$ xhost +si:localuser:root
would probably fix it.
mutter could presumably fix it with an XAddHost call. Probably going to miss 7.5 at this point.
