My Uconsole hangs up on boot - the graphic desktop comes up and just hangs - no mouse , can ssh into the unit - I’m debating on troubleshooting the gui versus making a new image - I’ve dropped it twice and I may have glitched the image on the SSD card. (first time I dropped it I had to re-seat the CPU)
Have you tried plugging in an external mouse or keyboard? If you can SSH into the computer, it would seem more like a connection issue with the keyboard module. It may be worth it to take apart your console and re-seat everything; maybe clean out any dust from the year of use.
I hope you get it figured out.
