Can you open other X (GUI) applications in WSL?
If not this may be of use

thank you very much for your link! I work it out!
but it didn't solve my trouble in wsl. because my target is displaying image embed into the ranger or nnn software, not pop a window to display(not convenient), so I can completely use wsl to develop in my job. I found this is impossible because wsl it self not support graphic now, so it's impossible to display the image via a software based on wsl.
so I drop the target at present, solved this by another way to browser images or other docs in windows explorer.
I write a simple sh script to open a explorer with current position in wsl shell, so I can quickly switch to windows to browser any file from wsl.
