I'm on a oneplus 7 pro. Installed NH 2021.1. kex worked perfectly, but some HID functions didn't. I ran apt update && apt dist-upgrade. After that HID works, but when I click on start server for kex the terminal screen shows and says server started, but when I click refresh the server isn't started. I've done everything I can read to no avail, evenchmod +x ~/.vnc/xstartup
