Description Nistratov Stepan 2017-04-03 20:45:58 MSD
Good day!
Description of problem:
Inverted screen brightness control in KDE4.
When the percentage of brightness on control-bar increments, the actual brightness of screen decrements, and vice versa. Its actual for software control bar (on desktop control or in power settings), and for keyboard control (with "Fn" key). When brightness is 0% or 100%, the screen backlight get off.
На русском:
Добрый день!
Инвертированное управление яркостью экрана на KDE4.
Когда процент яркости экрана на панели управления увеличивается, фактически яркость экрана уменьшается, и наоборот. Справедливо для управления на панели (на рабочем столе, либо в настройках электропитания) и для управления посредством клавиатуры (в сочетании с клавишей Fn). Когда яркость установлена на 0% либо 100%, подсветка экрана отключается вовсе.

Version-Relase number of selected component (if applicable):
ROSA Fresh 8.1, KDE4.
Kernel:
Linux abs-laptop 4.4.48-nrj-laptop-1rosa-x86_64 #1 SMP PREEMPT Fri Feb 10 12:12:29 UTC 2017 x86_64 x86_64 x86_64 GNU/Linu
Actual for 4.4  and 4.7 kernel versions, another kernel versions not tested


How reproducible:

Попробуйте, воспроизведётся ли проблема на ядре 4.9, которое сейчас тоже есть в репозиториях.

Если воспроизведётся, то после этого загрузите нам данные о системе с помощью hw-probe: https://linux-hardware.org/index.php?view=howto
