[xcrysden] Running xcrysden on windows subshell for linux (wsl)

[Matic]

Hi Jeremy,

you need to install XMing, if you don't have it already. Then you can 
test the command "export DISPLAY=:0" simply by typing into the terminal 
(that will only work for the current session).

I suggest you paste it into your ~/.bashrc file; open it with an text 
editor and just paste the command there and then type "source ~/.bashrc" 
into the terminal (or restart the application).

You can test if the DISPLAY variable is set correctly by "echo $DISPLAY" 
(it should output :0)

Best,

Matic
