One problem i had with my dell is not really a critical issue more of an annoyance. The fancy eject button just above my the dell’s keyboard those not work. I would have to manually right click and eject any mounted cd from its icon on the desktop. it would make my life easier if solved. well i have found a solution
and run this command.
sudo gedit /etc/sysctl.conf
now add this line to the bottom of the config text file that opens
# allow eject of cdrom using eject button
save and close.
The eject botton should now work.
