Bug ID: 392286 Summary: Display turns on twice after going into powersaving mode Product: Powerdevil Version: 5.10.5 Platform: Kubuntu Packages OS: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general Assignee: plasma-b...@kde.org Reporter: andy...@mail.ru Target Milestone: --- I have two displays attached to my GTX980, the main display on DisplayPort-4 and a secondary display on HDMI-0. The system is configured to turn off the displays after 10 minuses of inactivity. PowerDevil turns off the displays as expected. However, ~5 minutes after that the main display on DP-4 turns on only to show that there is no signal (the display's on-screen message) and turns off again. Another ~5 minutes later this happens again. After that the display stays off as it should be. The other display on HDMI-0 is actually a TV and it shows a blank screen all the time with no activity while DP-4 wakes up. This only happens when the display turns off for power saving. It does not happen if I issue `xset dpms force off` from the command line (the displays turn off and don't wake up). This is 100% reproducible and I'm sure it's not due to some activity (e.g. an event from the mouse) because when the display wakes up it does not show desktop/lock screen. I would like the display to not wake up like that. Kubuntu 17.10, x86_64, Nvidia driver 390.42, GTX980, DP-4 display is NEC EA275UHD. -- You are receiving this mail because: You are watching all bug changes.
