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 --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: bjorn 1993 F.... pulseaudio /dev/snd/controlC1: bjorn 1993 F.... pulseaudio /dev/snd/controlC0: bjorn 1993 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: X-Cinnamon DistroRelease: Ubuntu 20.04 HibernationDevice: RESUME=UUID=39f2962e-3115-438f-a447-03558db08edb InstallationDate: Installed on 2018-06-08 (725 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) MachineType: Dell Inc.
