Title:
screen brightness up/down keys not working in LENOVO IdeaPad 5 15IIL05
Status in linux package in Ubuntu:
Incomplete
Status in xorg package in Ubuntu:
New
Bug description:
The keys marked for brightness control on the keyboard are supposed to be
Fn+F5 (down) and Fn+F6 (up).
But pressing them does not have any effects.
Volume control keys Fn+F1 (off), Fn+F2 (down), Fn+F3 (up) all do work, and
KDE shows appropriate indicators when they are pressed.
I know this is a popular problem with Lenovo laptops.
I use Ubuntu 21.04 Hirsute on built-in NVMe, but Ubuntu 20.04 booted from USB
flash drive also does not allow me to control screen brightness.
Hardware and OS information will be collected on Apport request and attached
here.
