Setup Cypress on WSL ubuntu for windows 10
Got the idea from here: https://github.com/microsoft/WSL/issues/4106#:~:text=you%20may%20also%20need%20to%20launch%20vcxsrv%20with%20the%20-ac%20argument.
If you have XLaunch running - exit it by double-clicking on the icon in the taskbar and click Exit;
Then open your start menu > right-click XLaunch shortcut > More > Open file location;
Right-click XLaunch shortcut in the Explorer window > Properties;
Add " -ac" without double quotes right after the closing double quote in the Target field - i.e. for me it was "C:\Program Files\VcXsrv\xlaunch.exe" -ac;
Click ok
Now run Cypress again. Yay! Ran for me :)
For me, this was caused by having a WSL1 image (despite having WSL2 installed). You can check via wsl --list --verbose. Follow steps here to convert to WSL2.
