Bug ID: 494157
Summary: Switching to HDR with Kscree.doctor does not work
(regression)
Classification: Plasma
Product: KScreen
Version: 6.1.5
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kscreen-doctor
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
I was using kscreen-doctor to enable and disable HDR of my monitor via a
script.
If it is disabled i send:
kscreen-doctor output.1.hdr.enable
Following output is shown:
screen.doctor: setop exec returned KScreen::Config(
KScreen::Output(1, "DP-1", connected enabled priority 1, pos: QPoint(0,0), res:
QSize(3440, 1440), modeId: "1", scale: 1, clone: no, rotation:
KScreen::Output::None, followPreferredMode: false) )
if it is already enabled i send:
kscreen-doctor output.1.hdr.disable
Following output is shown:
screen.doctor: setop exec returned KScreen::Config(
KScreen::Output(1, "DP-1", connected enabled priority 1, pos: QPoint(0,0), res:
QSize(3440, 1440), modeId: "1", scale: 1, clone: no, rotation:
KScreen::Output::None, followPreferredMode: false) )
Monitor: Alienware 3423AWDF
I am using a plasma wayland session.
STEPS TO REPRODUCE
1. Use kscreen doctor to enable hdr
2. See the screen flicker shortly and change to HDR mode
3. Check if hdr is enabled after that in systemsettings (it should not) and if
it does work (it should not).
4. Enable, disable, enable HDR again even leads to a completely washed out
screen.
OBSERVED RESULT
The monitor does flicker shortly and gets set to HDR mode but it is not working
correctly.
The HDR setting for the display in system settings does not change.
EXPECTED RESULT
The monitor goes black (a modeset ?)and comes back switching to HDR ( like it
happens when you change the HDR setting in the system settings) and HDR works
as expected.
The HDR settings shows enabled in system settings.
Switching HDR on/off via systemsettings instead of kscreen-doctor works
absolutely flawless.
Sadly doing it via a keyboard shortcut that way is not possible.
In the past kscreen-doctor was causing the same behaviour as using the
system-settings page for the display and worked fine.
