<div>
<pre>After upgrading to linux 3.14 x86_64 on ArchLinux, using either the fn keys or
the slider provided by gnome shell will not change the display brigthness on my
Dell XPS 13 (L322X model) with Intel IvyBridge integrated vido card.
However, after executing the following command, the display brightness
adjustments (nf key, slider menu etc) starts working again:
su -c "echo 0 > /sys/class/backlight/intel_backlight/brightness"</pre>
