I think most likely the cause here is an event from a mouse or keyboard -- even if you're not touching them. Please try:
1. Unplug all mice and keyboards. 2. Wait for the screen to turn off. 3. Does it turn back on? Similarly spurious wakeups could come from apps (please test with no apps running), or from the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1852101 Title: Monitors keep turning on when in power saving mode, every time.
