I have Kali running on a Raspberry Pi 3. I dont know what I did to mess up the VNC Server but now all of a sudden I can connect to the Raspberry Pi VNC but the screen is frozen, I can move the mouse around but when I click on anything nothing happens. If I close the session and reopen it the things I clicked earlier show up but then again is frozen. So it reads the commands but the screen apparently wont refresh. I tried uninstalling and reinstalling, tried TightVNC and TigerVNC and they both do the same.
