Bug ID: 435754
Summary: Keyboard backlight does not turn back on after opening
laptop lid if it was already on before closing the
lid.
Product: Powerdevil
Version: 5.20.5
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: fishnet37...@gmail.com
Target Milestone: ---
SUMMARY
I have a Lenovo ThinkPad P72 with Gentoo Linux installed on it. In KDE's power
management settings, I have the keyboard brightness enabled and set to the
maximum for when the AC adapter is connected. If I close the lid and then
re-open it, the keyboard backlight remains off. I also have it configured to
do nothing when the lid is closed with the AC adapter connected.
STEPS TO REPRODUCE
1. Enable the keyboard backlight in the Power Management settings.
2. Close the laptop lid.
3. After a couple seconds, open the lid again.
OBSERVED RESULT
Keyboard backlight remains off.
EXPECTED RESULT
Keyboard backlight respects the Power Management configuration.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Gentoo Linux
(available in About System)
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.80.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
I can work around the issue by installing acpid and having it configured to
turn the backlight back on when the lid is opened, but I don't believe I should
have to.
