https://bugzilla.suse.com/show_bug.cgi?id=1218393 Bug ID: 1218393 Summary: Weird screen blanking (power mgmt?) issue Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: gfx-bugs@suse.de Reporter: rs.opensuse@spitzenpfeil.org QA Contact: gfx-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- My screen blanks after screen power mgmt kicks in - as expected. Unfortunately the timer doesn't seem to reset. As long as I move the mouse (even after switching to a console) the screen stays on, once any screen update stops, it goes dark. Currently I to run 'xsnow' !! to keep the screen updating, so it doesn't go dark all the time. This is not fun :-( Where to look?

Once screen updates stop it goes dark all the time. After logging off (KDE) it reverted to normal. Unfortunately this is not highly reproducible, but I would really like to avoid buying a new machine. -- You are receiving this mail because: You are on the CC list for the bug.

Interesting: the xclock window doesn't have to be on the laptop's screen, it can be anywhere and it still helps. -- You are receiving this mail because: You are on the CC list for the bug.

I've had a couple of days "peace", but now it's back. It may very well be a hardware defect. I'm getting a lot of these log entries. --- May 27 18:27:14 linux-1p8x kernel: i915 0000:00:02.0: [drm] HPD interrupt storm detected on connector eDP-1: switching from hotplug detection to polling May 27 19:02:47 linux-1p8x kernel: i915 0000:00:02.0: [drm] HPD interrupt storm detected on connector eDP-1: switching from hotplug detection to polling --- Moving the display hinge or shaking the laptop etc. doesn't change anything, nor does it trigger the issue. -- You are receiving this mail because: You are on the CC list for the bug.
