linux – WSL – GEDIT Unable to init server: Could not connect: Connection refused

You need an X server to run graphical applications like gedit.
I use VcXsrv or Xming on my Windows desktops, both are very small and easy to install,
but there exist other servers like Cygwin/X.

Short instructions for VcXsrv/Xming:

  • download and install the Windows package
  • start XLaunch or Xming
  • export the DISPLAY variable in your WSL terminal and start gedit

    export DISPLAY=0:0
    gedit
    

I have the problem that some checkboxes in gedits preferences are not working (dconf error, I dont care), but other than that the editor is usable.

To fix this problem

Step 1- Download and Install this Windows X Server https://sourceforge.net/projects/vcxsrv/

Step 2- Open XLaunch

Step 3- Select Full screen option

Step 4- Choose Start no client option

Step 5- Simply do next and finish

Step 6- Open terminal and type :

export DISPLAY=0:0                                 
gedit filename

In case your Linux machine is available with host name = hostname and youd want to ssh into the hostname and then open gedit then execute the following commands:

  1. Enable X11Forwarding in the ssh server
[hostname] $ vim /etc/ssh/sshd_config
             # and set X11Forwarding to yes
             X11Forwarding yes
  1. Set the DISPLAY env in the client terminal and then ssl with -X flag
export DISPLAY=0:0
ssh -X [email protected]
                                 
[hostname] $ gedit filename

Its probably because you are running it with root user.
Run it as non-root user.

(If you dont know that if you are running it as root or not, enter the command below and if it returns 0, it means you are root and you must to login to non-root user: id -u)

(If you had run sudo su or something like that, It means you are root and you must use exit to go back!)
