Package: hotkeys
Version: 0.5.7.4-0.1
Severity: normal
Tags: patch
This patch adds support to hotkeys for controlling LCD backlights using
the RandR extension. The code is copied from xbacklight, so it does the
same fancy fading between brightness levels.
This patch assumes you've applied my alsa patch first. Like in the alsa
patch, I've added -lXrandr -lXrender -lX11 to the link line directly,
as I don't feel like messing around with autoconf.
BTW, the copyright file probably needs to be updated to mention Keith
Packard's copyright, as well as the amixer copyright stuff from the alsa
patch. xbacklight is BSD licensed.
