[SOLVED] Jasność monitora-brak regulacji HP Pavilion

[NIEDOBRY]

0

Witam. Problem to brak reakcji suwaka na poziom jasności w HP-ku. Sposób z wątku https://forum.linuxmint.pl/showthread.ph...+regulacji nie działa.
Ktoś coś doradzi? Przygodę z Linuxem rozpocząłem wczoraj wieczorem, więc bardziej niż zielony jestem.

Kompletnie nie wiem, gdzie czego szukać ( i jak ) w konfiguracji sprzętowej.
