14.04: CD-ROM eject key does not work [SOLVED]

[Tobias Krais]

Hi together,

I finally found a solution:

1. Go to https://launchpad.net/~dell-team/+archive/ppa and download 
dell-wmi-dkms 0.2~jaunty1. Install the package.
2. Append the following lines to /etc/sysctl.conf:
-----%<-----
# Unlock the CDROM eject button
dev.sr0.lock=0
-----%<-----

Good luck for everyone having the same problem!

Greetings,

Tobias
