Title:
Unable to suspend displays when external display connected
Status in xorg package in Ubuntu:
Incomplete
Bug description:
I'm running Ubuntu GNOME 16.04 on a laptop (HP Elitebook Folio 1020 G1
SE) with an external display (DELL U2713H) via HDMI, and I cannot
suspend displays with this configuration kept.
1. I type Win+L to lock the session
2. Laptop shows locked screens, then all display outputs get suspended
3. External display detects no input signal and enters power saving mode
4. Laptop somehow detects the external display being disconnected, wakes up
and resizes the desktop to single-display configuration (2560x1440)
5. External display wakes up on input signal from the laptop
6. Laptop detects the external display being connected, resizes the desktop
to dual-display configuration (5120x1440)
7. Loop over 2-6
On Ubuntu GNOME 15.10 it worked as expected, after step 3 all displays
kept suspended until I touched my keyboard or mouse.
