I am using Windows 10 on my Surface Pro. I installed Cygwin and also included some useful Nedit packages (gvim, emacs, vim, g ++). However, when I run gvim, I get the “Unable to unlock screen” message. The same thing happens when I am suffering from nedit. When I did $ DISPLAY with echo, I was not displaying anything, so I set each of our DISPLAYs to: 0.0. I still cannot “open the ad”. I tried uninstalling and reinstalling Cygwin but I have the same problem…

Unix GUI programs are viewed through the X server. Cygwin is not automatically an X server natively. You need to replace the xorg-server and xinit packages and run startxwin accordingly.

Since X-System 1.17, the server does not listen for TCP / IP connections by default, but only opens local connections on the Unix arena socket.For local clients use DISPLAY =: 0.0 instead of DISPLAY = localhost: 0.0 , DISPLAY = 127.0.0.1: 0.0 , DISPLAY =: : 1: 0,0 etc.
If that doesn’t work (on a remote connection): use someone else’s -listen tcp option to restore the previous behavior so that the X server is on a socket, TCP / IP could respond so well, for example
startxwin - -listen tcp Finally, don’t forget to run xhost + again in Cygwin terminal.

- Open XLaunch, select “Multiple Windows” and set the display number (any).
- In Cygwin
export DISPLAY = [regardless of your display number]. - Start your personal program with

- Install the
xorg-serverandxinitpackages. Run these commands in Cygwin in a nice shell window:
startxwinDISPLAY = localhost: 0.0 xterm
But for Joe, the standard CygWin console is a nice musical chime. like XTerm, so I keep using it.

Try running xhost + localhost in terminal and then run the request again. This allows all users on your system (ie Root) to open public windows on your screen. Make sure to – use localhost rather than, for example, as it is safer to assign connections from localhost only than from anywhere.

Make sure someone has installed the openssh package.Start Cygwin / X.Make sure the DISPLAY environment variable is correct. (Run ssh instruction to connect to remote computer:Enter your password when prompted by ssh.Your SSH session should now issue a shell prompt for the entire remote computer.
