c...@ccss.de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |c...@ccss.de --- Comment #2 from c...@ccss.de --- Same here, too. Even when the display is switched off using `xset dpms force off` it switches back on after a few seconds. After long searching I found this thread: https://www.linuxquestions.org/questions/linux-hardware-18/monitor-doesn%27t-stay-in-standby-when-using-a-dp-cable-4175672795/ with the suggestion to disable kscreen2 - et voilà, when kscreen2 is disabled it works, the screens remain off.
