Dell XPS 13 9360 Backlight


I'm running Fedora 26 alpha von this quite nice laptop.
What I really don't understand is the function key functionalities.

When I login GNOME all the function keys work like sound adjustment and backlight brightness. When I login XFCE none works. When I login cinnamon only sound adjustment works.

What do I need to do in order to get backlight brightness adjustment keys working in Cinnamon?
I already figured out that in /sys/class/backlight/intel_backlight/ the settings are stored and can be manipulated in the file backlight.

Thank you

@pebrille you could try removing the "nomodeset" parameter from the boot parameters

this Dell ultra-portable has intel graphics, not nvidia. adding nomodeset would never have been necessary so equally it shouldn't be there to remove.
