If that fails, switch your login session to "Ubuntu on Xorg" (or your distro’s X11 fallback) from the login screen. This isn't a hack; it’s a temporary truce.

AnyDesk isn't crashing. It’s looking at your graphics stack and saying, "I don't speak that dialect."

Copy the output after Modeline . It will look something like: "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync

If you are trying to access a remote machine that is currently at the login screen (unattended access), AnyDesk often fails because the display server hasn't fully initialized for a user session.
