I use Ubuntu 17.10.
When I start gedit, virt-manager as root I get a dubious error message:
gtk warning cannot open display :0.0
I read many posts but none works with Ubuntu 17.10.
Thanks for any help.

By default 17.10 does not allow root to access your display.
Try the command xhost +si:localuser:root
then launch gedit with root privilege.
There is an alternative method by typing these commands:
su -
gedit
When you will type 1st command, It will prompt for the password.
Note that by this way gedit will open as the root user.
