Public bug reported:
Clusterssh worked fine since "ages", but recently I have the following
problem if I try to start clusterssh from terminal:
Connection to server failed -- (version 11.0)
Authorization required, but no authorization protocol specified
at /usr/share/perl5/App/ClusterSSH/Window/Tk.pm line 57.
It seems the following "workaround" fixes it temporary:
xhost +si:localuser:$USER
But what I don't understand, that I can start "xterm" or any X11
application without problem from terminal (the system running Wayland,
but XWayland works otherwise), only clusterssh doesn't work without
giving that "xhost" command first, what I can't understand why. Since
all other X11 apps works, I concluded this is a bug in clusterssh.
