Summary0006827: kali-defaults* 2020.4.6 has set X11 as the default display manager
DescriptionI just got the kali-defaults and kali-defaults-desktop upgrade from 2020.4.5 > 2020.4.6 and lost my second screen (HDMI) after the reboot.
xrandr is not detecting output save from the built-in monitor, and windowing system shows X11 as opposed to GNOME in Settings>About

gdm3 is still the default display manager in /etc/X11/default-display-manager, it's also selected on the login screen, but it falls back to X11 immediately after login.
Second graphics card is an NVIDIA GTX 1660 Ti (no drivers installed)
Steps To ReproduceUpgrade kali-defaults and kali-defaults-desktop to 2020.4.6 and reboot with a second monitor connected via HDMI

Update: this is not a bug; Wayland is now disabled on startup (trouble with NVIDIA drivers, of course)

If you still need Wayland, here's how to get it back:

# If you want to try out wayland, you have to disable that systemd
# snippet and restart gdm:
# mkdir -p /etc/systemd/system/gdm.service.d
# ln -sf /dev/null /etc/systemd/system/gdm.service.d/disable-wayland.conf
# rm -f /run/gdm3/custom.conf
# systemctl daemon-reload
# systemctl restart gdm

Many thanks to Hertzog for the detailed documentation!

This little thingy has broken my kali whatsoever. Only console.

Disabling that systemd snippet fixed the issue. LOL.
