I had the same issue after upgrading to ubuntu 22.04 and the logs showed the following error.
Failed to connect to the screen saver: Error al llamar StartSereviceByName para org.gnome.ScreenSaver: Failed to execute program org.gnome.ScreenSaver: No such file or directory The missing file was /usr/bin/gjs which I was able to solve by installing the gjs package. After restarting session the display powered off as espected. I hope your problem is the same and you can solve it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1971434 Title: Display powersave only blanks, but does not turn off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1971434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
