<pre>This is still in 3.18.6.
A friend of mine has a laptop from the same product family SAMSUNG
900X3C/900X3D/900X3E/900X4C/900X4D running Debian Wheezy (contrary to my Debian
Jessie) without an external monitor connected (I have one connected on HDMI):
There with all kernel >3.14 (from Debian backports) the GDM login screen is
black and brightness not adjustable at all until she logs in. Disabling
intel_backlight also fixes the problem there.
So my proposed patch would help both of us.</pre>
