get screensaver to work on extended desktop screen

With both commands, the screens were visible rather than remaining black. Both results were the same: both monitors would go black, then one would power down and when the other powered down, they would both power back up. I suspect it isn't relevant to desktop installations. Suggests using setterm on an Ubuntu Server installation. How do I enable console blanking and display power save on a laptop server install?.My HDMI monitor does not contain such an option to disable, so sadly this is a no-go. Proposes a workaround solution to disable the auto input select option on the monitor. Monitors do not turn off (enter powersave mode) after screen blanking.A review of some of the relevant questions: It looks like this may be an ongoing issue with multi monitor setups. Prefer blanking: yes allow exposures: yes HDMI-A-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 521mm x 293mmĭisplayPort-0 disconnected (normal left inverted right x axis y axis) HDMI-A-0 connected 1680x1050+1920+0 (normal left inverted right x axis y axis) 474mm x 296mm

Both screen remains black, though, with only their backlighting and the mouse pointer visible. When the other monitor goes into standby, the first one powers back up and then the other powers up.

After a minute, both monitors slowly fade to black. Dual monitors, one connected via HDMI, the other via DVI. Ubuntu 20.04 21.10, fresh install, that is now updated to 22.04. Settings -> Power -> Blank Screen set to 1 minute
