Following instructions on https://wiki.kubuntu.org/Kernel/Debugging/Backlight
I have tried in /etc/default/grub: kernel parameters acpi_backlight=vendor, thinkpad-acpi.brightness_enable=1.
I have tried /usr/share/X11/xorg.conf.d/10-brightness-control.conf: Option "RegistryDwords" "EnableBrightnessControl=1"
I have tried editing /sys/class/backlight/acpi_video0/brightness with tee
None of these have enabled brightness control. If I boot with integrated graphics instead of Nvidia, it works fine. (Note: this laptop has Optimus). Any further suggestions?
