I've been running anydesk and teamviewer on my headless ubuntu (18.04LTS) box for a while now (over 6 months) without issue. I had to set up an xorg.conf to allow things to run headless over anydesk or teamviewer. I've had an issue crop up in the last week where anydesk will display the error remote server display not supported
and refuse to connect. If i plug the box into a screen, it will allow it to connect. I've seen others with the same issue being attributed to wayland, but when checking my desktop session is running in X11 so its not wayland.
Any idea where i should start?
