Title:
20.04 i915 laptop external monitor doesn't resume from power-save,
must open lid to turn it on
Status in linux package in Ubuntu:
Confirmed
Bug description:
Dell 5520 laptop -> Dell Thunderbolt dock -> HDMI -> external monitor.
Running 20.04, i915 driver.
Laptop lid closed, using external monitor only. When external monitor
turns off (after sleep-display-ac), keyboard/mouse activity should
turn it back on, but do not. Opening and closing the laptop lid does
turn the external monitor back on. Laptop is not suspended; I can ssh
in from another machine.
Happy to collect any additional information.
To reproduce:
- On Dell 5520 laptop connected to Dell Thunderbolt dock connected to
external monitor via HDMI
- Close laptop lid
- Use external monitor, external keyboard, external mouse
- Leave system idle for "sleep-display-ac" time
- System puts external monitor in power-save mode
- Move mouse, type on keyboard
- No response, external monitor remains in power-save mode
- Open laptop lid
- External monitor turns on
- Close laptop lid
- External monitor remains on, I'm able to work as usual
