My work machine runs Ubunutu 18.04. I'm trying to get my monitors to sleep and not having much luck.
I opened the Energy Saving module of System Settings and found the Screen Energy Saving was checked (even though my monitors don't sleep). I turned the Switch off after value down to 1 minute and waited. After a minute, the monitor displays the no signal warning and powers down to sleep mode. About 15 seconds later, with no discernable input, the main monitor wakes up followed by the secondary monitor maybe 5 seconds later. After the self restart, neither monitors will go to sleep again unless i manually reapply the setting. Rinse and repeat.
I'm a fairly experienced computer professional, but new to Ubuntu> i'd appreciate any ideas on how to debug and correct this somewhat annoying problem.
