GUI programs connect to the display defined by the $DISPLAY environmental variable. The general format of the error is Could not open display $DISPLAY Since, in your case, the error says (null), this means that $DISPLAY is not set. You therefore need to: If you are logging in to a remote machine using something like ssh, you will need to export the $DISPLAY of your local machine and tell the remote computer to display GUI programs there. This can be done with the -X or -Y options of ssh: ssh -Y root@10.251.56.90 As explained in man ssh: -Y Enables trusted X11 forwarding.

Apr 26 '15 at 16:50 @A.B. I should clarify that this is not via ssh. It's on local host in a very normal terminal window. Infact opening gparted from the application menu has the same result. –d_inevitable Apr 26 '15 at 16:53 You shouldn't have to use gksu to run GParted. gparted uses polkit to get elevated privileges. –muru Apr 26 '15 at 16:59 @muru when I run gparted without gksu I get Root privileges are required for running gparted. –d_inevitable Apr 26 '15 at 17:17 Ok, try gparted-pkexec (without gksu) or gksu gpartedbin. –muru Apr 26 '15 at 17:39 | show 3 more comments 1 Answer 1 active oldest votes up vote 7 down vote Try running xhost +localhost in your terminal, and then running the command again. This lets all users on your system (i.e. root) open windows on your screen. Make sure to use +localhost and not simply +, as it's more secure to just allow connections from localhost than from anywhere. To make this permanent, edit the ~/.xinitrc file like this: Run gedit ~/.xinitrc Edit the file to look like this (it should be empty to being with): #! /bin/bash xhost +localhost & Now save t
