a remote server, I'm getting the "cannot open display:" error, as shown below. How do I fix this? For example, while launching the gedit on remote server, I got the following message. (gedit:3658): error unable to open display Gtk-WARNING **: cannot open display: I get similar message when I try to open any error unable to open display glxinfo GUI application. For example, launching Oracle Installer on remote server also gives the "cannot open display" error. Answer: You can fix the error unable to open display (null) "cannot open display" error by following the xhost procedure mentioned in this article. 1. Allow clients to connect from any host using xhost+ Execute the following command to disable the access control, by which you can allow https://bbs.archlinux.org/viewtopic.php?id=108695 clients to connect from any host. $ xhost + access control disabled, clients can connect from any host 2. Enable X11 forwarding While doing ssh use the option -X to enable X11 forwarding. $ ssh username@hostname -X Enable trusted X11 forwarding, by using the -Y option, $ ssh username@hostname -Y 3. Open GUI applications in that host After opening ssh connection to the remote host as explained above, you can open any GUI application which http://www.thegeekstuff.com/2010/06/xhost-cannot-open-display will open it without any issue. If you still get the "cannot open display" error, set the DISPLAY variable as shown below. $ export DISPLAY='IP:0.0' Note: IP is the local workstation's IP where you want the GUI application to be displayed.

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. Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls. -X Enables X11 forwarding. This can also be specified on a per-host basis in a configuration file. If this is your local machine, you need to install a graphical environment. If one is already installed, assuming a default Ubuntu setup, you ca
