Bug ID: 508780
Summary: Feature Request: Shortcut to switch between SDR and
HDR, including notification
Classification: Plasma
Product: plasmashell
Version First 6.4.4
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Brightness and Color widget
Assignee: [email protected]

Target Milestone: 1.0
It would be nice to have default keyboard shortcut for toggling between HDR and
SDR display mode as well as an on-screen prompt to alert a user which mode
they're using. Currently, users have to open display settings to change modes
and refer back to it if it's not immediately obvious which mode is being used.
I personally created a Meta+Alt+B (same as Windows) shortcut that launches a
bash script that relies on ansifilter, kdialog, and kscreen-doctor to execute
the following for switching between modes, but it requires editing when I
change ports:
kdialog --title "Enabling HDR" --passivepopup "HDR has been enabled" 6 ;
kscreen-doctor output.HDMI-A-1.hdr.enable output.HDMI-A-1.brightness.100 ;
kscreen-doctor output.HDMI-A-2.hdr.enable output.HDMI-A-2.brightness.100 ;
The 6 second timeout is important for displays that blank for several seconds
when switching between modes. Windows' ~2 second prompt is completely useless
for one of my monitors. I've personally not noticed a difference when enabling
or disabling wide colour gamut with HDR enabled so I also include
output.HDMI-A-1.wcg.disable
Is this a trivial feature to include in KDE Plasma itself? Adding a GUI toggle
to the Brightness and Colour widget would also seem like a good idea.
Thank you!
