Hi,
I’m having weird problem with setting the screen brightness level.
Setting it anywhere between 0 and 40% doesn’t affect brightness at all, above 40% it gets progressively brighter until it hits 100% then screen gets completely black,zero light.
I’m not sure when problem exactly appeared.
I already tried:
- Changing
"/sys/class/backlight/intel_backlight/brightness"
value manually, had the same effect as using slider. - Downgrading kernel to 6.2.9 and mesa to 23.0.1-2, that did nothing.
- Changing
"acpi_backlight"
from"native"
to"vendor"
and"video"
,"vendor"
did nothing,"video"
fixed black screen at max level but still had that weird “no effect” zone between 0 and 40%.
Problem was noticed on HP EliteBook 8460p with Intel HD3000 running Endeavouros XFCE.
