apport information

** Description changed:

- I cannot change the screen brightness on my HP Elitebook 8560w. If I use
- the keys for changing the screen brightness (fn + f9 or fn + f10), the
- on-screen display appears and the displayed percentage changes as
- intended but the actual screen brightness does not change (i.e. it
- remains at full brightness). Similarly, if I do not use my computer for
- some time, the on-screen display appears and indicates the the screen
- brightness is reduced (lower percentage) but the actual screen
- brightness remains unchanged (at full brightness). I have this computer
- since November 2011 and I had always the latest Kubuntu version
- installed. Changing the screen brightness always worked until and
- including Kubuntu 13.10. However, it stopped working when I upgraded to
- Kubuntu 14.04. I have upgraded my computer's BIOS to the latest version
- (F.42) but this did not help. As I also experience another bug (1337579)
- with Kubuntu 14.04, I have upgraded the kernel to the upstream kernel
- (3.14.4-031404) and a mainline kernel (3.16.0-031600rc6) but the bug
- occurs with all three kernel versions.
