Hi all,
I have a brightness issue on my laptop, it's stuck at 100% all the time.
I tried using acpi_backlight=native as someone suggested in the forums here but this is not working.
If I use the brightness keys the sysfs gets updated but the brightness remains stuck at 100%.
Also xbacklight does not work, increasing or decreasing the brightness using it produces no messages and does not change the brightness of the screen.
the OSD always changes and reflects what is in the sysfs.
I have an intel and Nvidia 1070 qmax with the native drivers.
let me know if there are other missing info. I can do whatever is needed to track this down.
thank you very much

hi @DataDrake
I did upgrade over the weekend but unfortunately this is still not working.
I tried also all possible combinations of acpi_backlight, acpi_osi I found over the net to no avail.
it seems that the driver is somehow bound to the intel card even if I installed and use only the nvidia one. Also tried using only the intel driver, same results.
I also picked up the nvidiabl package and modified it for my system but also this one seems not to do the brightness trick, but I'm not really an expert in kernel drivers...
right now I resorted to using xrandr --brightness 0.5 but this is not really a solution.
thanks
