The "State of Wayland" page here says we have to Sign In with Xorg instead of Wayland.
How do I do that?
I'm using the free version on Linux: Debian 10 Buster - 64bit.
Okay, I'm running Debian 10 Buster and I went to /etc/gdm3/daemon.conf and uncommented the line:
#WaylandEnable=false
After reboot, it worked.
