Etherape does not detect display when running as root on Wayland

[Wise Melon]

When I run Etherape as a normal user it launches, but as my system is configured so that only root can capture, I am forced to run Etherape with sudo, however this means that the only output I get is this and that the program does not work as it does not launch and just exist after printing this:

    No protocol specified

    (etherape:2294): Gtk-WARNING **: cannot open display: :0

I am running Ubuntu GNOME 16.10 with GNOME 3.22 and this only started happening after I switched from Xorg to Wayland via the login screen.

See the response on this mostly unrelated bug: https://bugs.debian.org/818366

I suggested you file against gnome-shell (Ubuntu) when you asked for a specific place to report these kinds of issues. At least reporting there would allow for someone to triage them to where the bug probably exists. But usually, these aren't actually bugs in Wayland or GNOME so you can file directly against the affected package if you like.

Right, thanks for letting me know!

A report has been filed upstream: https://sourceforge.net/p/etherape/bugs/103/

They have added a new -Z option allowing the GUI to run as the specified normal user rather than as root and it works like this on my Arch system with Etherape version 0.9.15.
