Thank you for the patch. (I'm Italian, so I'm sorry for my bad English).
I had brightness problem in a Samsung R70, and I think you could add it in the list of computer were the patch works well. Infact it does. This is a great success for me, raeally thanks!!
I have now another problem:
I can now set brightness values with commands like
echo 50 | tee -a /sys/class/backlight/nvidia_backlight/brightness
but also with
were N in a natural number such that 15<=N<=100. This is quite useful because it don't need ROOT password.
The hot-keys of my computer can show the "brightness message" and move the bar, but i can't see any change neither in brightness nor in the value given by
nor in the value given by
Moreover it's quite useless the commands
because they decrease/increase the brightness of only one unit, that is very few.
There is a way to change the brightness value with the keys and to connect it with the default Ubuntu brightness manager (for example editing the code that Ubuntu use to change the brightness)?
Thanks for help,
