If you get an error (Tiger VNC) that says that Tiger can’t connect to Kex, do this at your WSL2 shell prompt:
kex stop
…then, start as normal. I updated my BAT file to do this automatically:
@echo off start /B x410.exe /wm set path=c:\Windows\System32;c:\Users\jeffr\AppData\Local\Microsoft\WindowsApps kali run if [ -z \"$(pidof kex)\" ]; then "kex stop; export DISPLAY=192.168.5.50:0.0; cd /home/jwinn; kex kill; kex wtstart; fi;"
