Starting with Ubuntu 17.10 GNOME Wayland is the default desktop environment. But the Peek Snap does not support screen recording on Wayland since the Snap cannot access the GNOME screencast DBus service.

There are two workarounds for this:

• Use X11 session instead of Wayland
• Install Peek from PPA

A fix is needed since this is causing a very bad user experience for Ubuntu users installing from the Ubuntu store. But for now I have no good idea how to solve this.
