Not working on GLX560M (Toshiba Qosmio X770-11C)

[Lustmored]

I tried under binary blob and now on nouveau (I prefer the latter) and it simply doesn't work.

I even added "acpi_osi=Linux acpi_backlight=vendor" to kernel, but no luck.

Is it still not working on version 0.80 ?

[Lustmored]

Unfortunately no change.

Is there any more info I can provide to help?

[guillaumezin]

Maybe you can try version 0.81. And if it still doesn't work, with version 0.81, try to load the driver with these command (warning, exit all programs, it can crash your computer):

sudo modprobe -r nvidiabl
sudo modprobe nvidiabl screen_type=3

[Lustmored]

when loaded with screen_type=3 function keys nor KDE still couldn't change brightness. Although changing in /sys/class/backlight/nvidia_backlight/ works!

Indeed 127 is very very dark (probably wrongly read maximum), but at least manually echoing to brightness does any change:

vindor nvidia_backlight # cat actual_brightness
17595
vindor nvidia_backlight # cat brightness
17596
vindor nvidia_backlight # cat max_brightness
127
vindor nvidia_backlight # echo 55>brightness

vindor nvidia_backlight # cat max_brightness
127
vindor nvidia_backlight # cat brightness
17596
vindor nvidia_backlight # cat brightness
17596
vindor nvidia_backlight # echo "55">brightness
vindor nvidia_backlight # echo "127">brightness
vindor nvidia_backlight # echo "17596">brightness
-su: echo: write error: Invalid argument
