When you call a command like this:
and you get an error message saying Cannot Connect to X Server, while if you executed that command without the sudo it would execute properly, you can resolve this issue by replacing “sudo” with “xgd-su -u root -c” resulting the following command:
xgd-su -u root -c someCommand
xdg-su provides a graphical dialog that prompts the user for a password to run a command as another user.
