[Bug 2062126] [NEW] Booting with laptop lid closed and external monitors on X11 causes the computer to sleep prior to login

[Jamie R. McPeek]

Public bug reported:

When powering on a laptop with the lid closed, connected to a dock which
is connected to external monitors, if gdm3 is going to run on X11, the
computer is suspended prior to the login screen being displayed.

Tapping a key on the keyboard wakes the computer out of suspend and
immediately shows the login screen on the external monitors as expected.

The computer does not suspend prior to login if gdm3 is going to run on
Wayland.

I'm encountering this issue with Ubuntu 24.04 beta, and believe it may
be related to the following systemd issue:
