I rarely use cd's on my laptop, but I recall having the same problem a few months ago. When I put a cd in my DVD drive nothing happens. It kicked in last time without me doing anything but I don't know what's wrong. I need to burn a cd with k3b but it gives the error "no optical device found".
My system is Fedora 20 x86_64.
Problem: CD's don't get mounted, when inserted in the drive nothing happens.
What can I do to resolve this problem?
UPDATE CURRENT:
Problem: cd's and dvd's are not working properly, since march they have been unstable as in "not mounting when inserted", "mounting when inserted but disconnecting at random"/"unmonting at random", when disconneted the disk is invisible to the system and I can't eject the disk.
I put a dvd movie in the drive yesterday, it got mounted in /run/media/username/MOUNTPOINT and eveything worked, then after a while it dissapeared, was not mounted anymore and I can not eject the dvd from the drive. This is how it is now, it's still in the drive, here are some commands that work on the drive as is now:

Expected output from above, this taken from the system, while a dvd was mounted, which is often successful, I need to know why the disks can disconnect/umount/dissapear at any time.

Behaviour of the dvd drive, disk's and dvd's are mounted in /run/media/username/MOUNTPOINT and work, but then they can disconnect at any time, and when they disconnect, they don't show up anywhere in the system, and I am unable to eject the disk.
When I close the lid, the laptop is set to "sleep", I did this 4 hours ago, and when I revoke it one hour ago the dvd in the drive got mounted in /run/media/username/MOUNTPOINT.
This is how it is now:

If you have an entry corresponding to your cd/dvd device in your fstab, try to comment it and reboot. Perhaps there is some interferences between automount and fstab options.
