Package: xbacklight
Version: 1.1.1-1
Severity: important

xbacklight has stopped working after some sid upgrade a couple of weeks ago.

(I've read about a seemingly similar issue in #563277 and just sat back and waited in the hope that the problem would just be intermediate and would get fixed when all parties involved adjusted to some name change, but it didn't happen...)

Running xbacklight with strace, i can spot both different variations mentioned in #563277:

% strace -f xbacklight|&grep -i backlight
execve("/usr/bin/xbacklight", ["xbacklight"], [/* 47 vars */]) = 0
writev(5, [{"\20\1\5\0\t\0\0\0Backlight\377\377\0", 20}, {NULL, 0}, {"", 0}], 3) = 20
writev(5, [{"\20\1\5\0\t\0\0\0BACKLIGHT\377\377\0", 20}, {NULL, 0}, {"", 0}], 3) = 20
write(2, "No outputs have backlight proper"..., 35No outputs have backlight property

The hardware involved is a Samsung NC10 for which lspci list the following graphics hardware:

00:02.0 VGA compatible controller: Intel Corporation Mobile 945GME Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)

According to /var/log/Xorg.0.log the xrandr is enabled.

The Gnome power manager brightness applet has stopped working, too, showing "Cannot get laptop panel brightness" when hovering over its icon.
