Eveyrtime when I'm trying to run any graphical software as root it won't work (i.e Synaptic, gedit) and I get this error :

No protocol specified
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused

(synaptic:32380): Gtk-WARNING **: cannot open display: :0`

I also tried running sudo -H and I get the same error, I executed export DISPLAY=:0 again, absolutely nothing.

I tried using gksudo instead of sudo too, no result.

I was thinking in reinstalling Mir, but how? I'm using Ubuntu 16.04

What environment are you running these commands under? What terminal app? It seems like some configuration was likely broken on your system. – dobey Nov 07 '17 at 21:03

But Mir is officially dead cannonical was using it but they abandoned it and start using Wayland – Paulo Botelho Nov 10 '17 at 08:25
Soooo, if I download Wayland, will Synaptic, gedit, etc etc going to work as root? – sticsk Nov 10 '17 at 16:01

@sticsk Not at all recommended, but you should be able to make them work as root under Wayland following this: Why don't gksu/gksudo or launching a graphical application with sudo work with Wayland? – pomsky Nov 11 '17 at 13:59
@pomsky It's working, I installed Wayland, I did that xhost thing and it's working. But do I need to remove the permissions everytime when I'm done using graphical softwares as root? – sticsk Nov 11 '17 at 20:49
