[SOLVED] Brightness settings not working

[ali3n0id]

Having a small issue turning down the brightness on my laptop, all the other function keys work except brightness. The key is properly assigned in global shortcuts and pressing the brightness buttons bring up the icon to show the brightness is being turned up or down but it doesn't actually change the brightness. I tried manually changing the brightness in power management but this also doesn't actually change the screen brightness/backlight. I tried using the 'xbacklight' command but to no avail. I'm running a Nvidia GeForce 1660Ti with the latest stable drivers. Any suggestions? TIA

I just wonder if it was working with Nouveau ..

Do you have /etc/X11/xorg.conf

or an Nvidia-related .conf file in

/usr/share/X11/xorg.conf.d/

?

Especially for the latter, you can try adding

Code: Select all

Option "RegistryDwords" "EnableBrightnessControl=1

just before EndSection.. i.e:


Section "OutputClass"
Identifier "nvidia"
...
...
...
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection


Or:


Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName ...
Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

Reboot.

( At least the xbacklight may begin to work )
