Yes I too have believed for years there must be a feedback problem causing this. The reason it's still not fixed is just that it's so rare... every time I try to debug it the problem doesn't happen at all.

When I manually run `xset dpms force off`, they do properly turn off and go to powersave mode. 1) Description: Ubuntu 22.04 LTS Release: 22.04 2) gnome-settings-daemon: Installed: 42.1-1ubuntu2 Candidate: 42.1-1ubuntu2 3) In Settings -> Power -> Screen Blank, set the inactivity period to 5 minutes. After 5 minutes, the screens should turn off. 4) Screens go black, but remain active and consume (too much) power. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu82 Architecture: amd64 CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME DistributionChannelDescriptor: # This is the distribution channel descriptor for the OEM CDs # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-somerville-bionic-amd64-20190418-59+beaver-osp1+X00 DistroRelease: Ubuntu 22.04 InstallationDate: Installed on 2020-07-04 (667 days ago) InstallationMedia: Ubuntu 18.04 "Bionic" - Build amd64 LIVE Binary 20190418-12:10 Package: gnome-settings-daemon 42.1-1ubuntu2 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 5.15.0-27.28-generic 5.15.30 Tags: jammy Uname: Linux 5.15.0-27-generic x86_64 UpgradeStatus: Upgraded to jammy on 2022-04-30 (3 days ago) UserGroups: adm cdrom dialout dip lpadmin plugdev sambashare sudo vboxusers video wireshark _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1971434/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
