问题
I'm using Ubuntu 18.04 as Windows Subsystem for Linux on my Windows 10 machine.
I've installed gedit without any errors or warnings.
But whenever I try to use the command gedit something (here something is a filename)
I get this error:
Unable to init server: Could not connect: Connection refused
(gedit:48): Gtk-WARNING **: 21:03:26.729: cannot open display:

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 gedit's preferences are not working (dconf error, I don't care), but other than that the editor is usable.

Step 2- Open XLaunch

It's probably because you are running it with root user. Run it as non-root user.
(If you don't 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!)
