Since I've upgraded from 20.04 to 22.04 two months ago, my screen switches to blank about five minutes without keyboard or mouse use. Impossible to read and concentrate on a complex task. Surprisingly, I found no similar questions so far even though I've been looking out now and then. Display and power management settings have no visible effect, even turn off display management on power seems unconnected to the configuration. This behavior shows up with 22.04, only, not in 20.04 and not in Windows 10 (parallel), hence it's buried in the 22.04 configuration. Has anybody else seen this behavior ... and more over, how to work around?
Best regards,
