Bug ID: 453699
Summary: Display goes into standby with adaptive sync active
Product: kwin
Version: 5.24.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: maugrer...@gmail.com
Target Milestone: ---
SUMMARY
My screen goes into standby saying "no signal detected" (on monitor OSD) with
adaptive sync enabled. If AS is set to "always" then it happens when simply
switching virtual desktop, otherwise is happens when gwenview is fullscreen,
for example.
This happens after switching to an unused TTY then switching display off
overnight. I didn't notice it before doing so.
Using dmesg provides nothing related. journalctl has a lot of
"krunner[3145799]: kf.plasma.quick: Couldn't create KWindowShadow for
View(0x7ffc2207b600)" and "xdg-desktop-portal-kde[3156325]: xdp-kde-background:
GetAppState called: no parameters" but nothing else from any time this
occurred. Please tell me how to gather other useful logs.
STEPS TO REPRODUCE
1. In Display Configuration, set Adaptive sync to "Always"
2. In a Wayland session, lock screen, switch to unused TTY, and turn display
off
3. Turn display on, switch back to Plasma session and either switch virtual
desktop (with apps open in each) or make a program (e.g. Gwenview) fullscreen
OBSERVED RESULT
Display goes blank briefly (switching VD) or blank and into standby mode (using
Gwenview).
EXPECTED RESULT
Smooth transition between virtual desktops or showing Gwenview as normal.
