Public bug reported:

A customer of mine gave me his old notebook because he bought a new one.
I trow in a new HDD and now the laptop is running an up to date Xubuntu
13.10 64bit. Everithing is working fine exept for the brightness
control: when I press the appropriate keys on keyboard the slider
appears on the upper right corner of the screen but even if it changes
the setting has no effect on the system . The notebook I have has an
Intel X3100 integrated video

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (primary) (rev 0c)

I tried different combinations on grub but no one resolved the issue.
Problem is I have not intel_backlight on /sys/class/backlight folder but
just acpi_video0 or dell_backlight (if I set acpi_backlight=vendor on
grub). Since I don't have intel_backlight folder I can't apply many of
the workaround found here and there.

------------------
effe@Vostro1310:/sys/class/backlight$ for i in /sys/class/backlight/*; do echo -e "\n $i"; cat $i/{brightness,max_brightness,actual_brightness}; done

 /sys/class/backlight/dell_backlight

------------------

If I increase the backlight the files are correctly updated:

------------------
 /sys/class/backlight/dell_backlight
7
7

------------------

acpi_listen works just on new mainline kernel 3.13.2 (tried bot generic
and lowlatency) on stock kernel there isn't output at all:

video/brightnessup BRTUP 00000086 00000000 K
video/brightnessup BRTUP 00000086 00000000 K
video/brightnessup BRTUP 00000086 00000000 K
video/brightnessdown BRTDN 00000087 00000000 K
video/brightnessdown BRTDN 00000087 00000000 K
video/brightnessdown BRTDN 00000087 00000000 K

Now I'm using xrandr to change the brightness:

xrandr --output LVDS1 --brightness 0.5

but since xrandr is a software overlay my battery life is horrible, I'm stuck on 100% brightness.
Beside this, sometimes the brightness slider appears spontaneously without pressing any keys but again with no effect.
