Y510P can't adjust screen brightness in Mint 17.3

Hi there,

I'm using Linux Mint 17.3  and I have this issue after installing Nvidia driver. I've tried many solutions, but nothing worked, and I think there is something wrong with my xorg.conf file.

 Here are the solutions I've tried:

1.

 

Spoiler
sudo nano /etc/default/grub
change line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash
video.use_native_backlight=1"
then save and exit and run
sudo update-grub

 

2.

Spoiler
Run this command in terminal:
sudo nvidia-xconfig
Run this command:
sudo gedit /etc/X11/xorg.conf
Under "Section" "Screen", before "EndSection" add this line:
Option "RegistryDwords" "EnableBrightnessControl=1"
So that section would look something like this (yours might not be exactly the same) :-
[[CODE: SELECT ALL
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
EndSubSection
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection ]]
Save file and reboot your system and Enjoy.

I found a temporary solution by decreasing the Brightness under Color Correction in NVIDIA X Server Settings app

 

and here is my current /etc/X11/xorg.conf

Please guide me to solve this annoying problem

Thanks in advance Smiley Wink
