14.04: CD-ROM eject key does not work

[Tobias Krais]

Hi ubuntu users,

I have a Dell XPS M1530 notebook. This notebook has a special key on top 
of the keyboard for ejecting a CD / DVD. But this key does not work 
anymore. Formerly I had to add this to /etc/sysctl.conf:
-----%<-----
# Unlock the CDROM eject button
dev.cdrom.lock=0
-----%<-----

Has somebody an idea how to fix this in 14.04?

Greetings,

Tobias
