The device supports.
OLED screens have no backlight, brightness cannot be controlled by changing backlight power in the traditional way. Instead, it can be controlled using PWM by enabling following option:
echo "options i915 enable_dpcd_backlight=1" >> /etc/modprobe.d/i915.conf
Alternatively, you can add a kernel parameter. For example, if you are using GRUB, edit /etc/default/grub with
Do not forget to update the grub configuration to apply the changes.
Hybrid Graphics (also known as Nvidia Optimus) Allows the system to use the integrated Intel graphics and the Nvidia GPU interchangeably without rebooting.
Brightness control under Hybrid Graphics should work "out of the box" with no kernel command line options necessary. If you notice brightness controls cease working, check that your BIOS settings are still for "Hybrid Graphics" and not "Discrete Graphics".
Discrete graphics means only the Nvidia GPU is available to the system.
Currently brightness control does not work with "Discrete Graphics" selected in BIOS.
