XPS 13 Infinity Max Brightness is Dim in Ubuntu

Question

Hi, I've just purchased an XPS 13 (not the developer edition) and installed Ubuntu 15.04 on it. Everything seems to be working fine (sound, wifi, hotkeys etc) except the screen brightness seems low even at the max setting. Colours that should be white (e.g. font in terminal) appear light gray. These are the brightness values; cat /sys/class/backlight/intel_backlight/max_brightness 937 cat /sys/class/backlight/intel_backlight/actual_brightness 937 cat /sys/class/backlight/intel_backlight/brightness 937 I've googled around but there doesn't seem to be any other people with this problem, apart from the adaptive brightness complaints (which could be the same problem I am having, although it seems consistently dim rather than changing). Thanks  Dan

I have exactly the same issue under Arch Linux 4.3.3.

I have the XPS 13 9350. Everything works fine, even changing the brightness to a lower value fades automatically.

Maybe the display is not brighter?
