Description Edward Sheldrake 2014-08-04 17:53:06 UTC

The ability to set the backlight via the xrandr property seems to have disappeared recently, the backlight property is no longer listed in the xrandr output.

But the backlight xrandr property is present if the brightness level is zero on starting X, so one line patch to follow.
