Created attachment 137791
Dell XPS13 9333 acpidump

I attached the acpidump of my Dell XPS13 9333.

If video.use_native_backlight=1 is not added to the kernel cmdline, the Fn keys are buggy: the brightness increases or decreases by one unit (max_brigthness is 937, so a variation of 1 is hardly noticeable) and I get not DE OSD.

With video.use_native_backlight=1, I get the OSD and a brightness variations of 10% as expected.
