Comment 22 for bug 1759950

Tested with the 19.10 daily (2019-06-22) amd64 build and the problem affects the live environment too.

Set x-p-m Lid Close action on battery to suspend and the 2nd lid close cycle results in DPMS=off when the GUI TTY is active.

As in comment #15 I monitored the LVDS DPMS state whilst switching between TTYs:

$ while true; do grep . /sys/class/drm/card0-LVDS-1/{dpms,enabled,status}; sleep 1; done

This also confirms the locker isn't implicated since, as I understand it, it is disabled in the live environment (and I saw no password challenge dialog even when specifically pressing the 'Lock' icon on the menu.)
