Bug ID: 510294
Summary: Laptop brightness is higher than indicated in
brightnessctl
Classification: Plasma
Product: plasmashell
Version First 6.5.80
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: 1.0
I have a laptop and external 4K screen.
Laptop is setup as having 30% screen brightness in 'power management > display
and brightness'
This setting was working ok (reproducible brightness) but is now lost after
sleep/standby.
The systray-brightness slider still says 30%, but the screen is noticeable
brighter.
Just touching the slider 'fixes' the effective brightness immediately (so i set
it back to point to exactly 30% again)
I did not yet check the output of 'brightnessctl info' directly after resume
(will do...)
One more thing:
in power management > display and brightness' i can only preset the brightness
for the laptop screen, not for the secondary monitor - although in systray we
have two brightness sliders. Is this intentional?
