[SOLVED] Brightness settings not working

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 )
