Synaptic failing to launch on 17.10 [duplicate]

  • 772

I have just done a clean install of 17.10 I am finding that synaptic package manager won't work: 

synaptic-pkexec
No protocol specified
Unable to init server: Could not connect: Connection refused

(synaptic:9019): Gtk-WARNING **: cannot open display: :0

Also finding that after installing Shotcut from Snap I get the following error: 'This program requires SDL2' I wonder if it's related? Any help would be very welcome.

Thanks!

17.10

    At your login screen, click the little cog wheel icon, and switch to gnome on xorg, and Synaptic (and some other apps) will now launch without difficulty. It's a Wayland problem.
