FWIW, I've never seen this on my Thinkpad X200 running Guix.  I also use
GNOME, although I use it under Wayland, by running

  XDG_SESSION_TYPE=wayland exec dbus-run-session gnome-session

from within a text console.  I don't use GDM, because our GDM package
does not yet support Wayland.

Note that GDM is enabled in my OS config and gets launched on every
boot, but I then shut it down manually using "herd stop xorg-server".
After doing so, I need to type "Alt+SysRq+r" to recover the use of my

It might be worth trying to do what I describe above, to rule out the
possibility that GDM is responsible.

What kind of machine is it?  If it's a laptop, I wonder if your laptop's
embedded controller is entering suspend mode automatically.
