Finally solved the backlight issue by installing the latest release of https://github.com/guillaumezin/nvidiabl/downloads - nvidiabl- dkms_0.73_all.deb
after intsalling it write in the terminal: sudo echo "nvidiabl" | sudo tee -a /etc/modules so that it automatically starts on bootup. and then you use this command to toggle the backlight in the terminal: echo 1 | sudo tee -a /sys/class/backlight/nvidia_backlight/brightness Important to note is that if you touch the settings in "Nvidia X Server Settings" it will cause Nvidia-bl to stop functioning. ** Description changed: + UPDATE: Heres a way to turn down the backlight + https://bugs.launchpad.net/ubuntu/+source/linux/+bug/934095/comments/34 + Fn+f6 & fn+f7 doesn't let me decrease/increase the backlight/brightness, only after putting the laptop to sleep and waking it up again does the backlight bar actually appear when I hit fn+f6 but it still doesn't decrease the backlight.
