Why is CD/DVD tray not opening?

Question

When I press the button on the dvd player, it doesn't open.

If I press it during the boot (before starting ubuntu), it opens fine.

So, what I have to do to eject the dvd?

Answer 1

Try this:

Steps:

1. sudo eject /dev/sr0
2. file /dev/sr0
3. sudo eject -i off

Answer 2

Some CD/DVD eject buttons send a signal, so that the operating system knows to eject. Some do not send a signal. So just pretend you do not have an ejection button on the device and use eject instead. If you are already on the command line...

eject

or maybe you may need to specify the device:

eject /dev/sdc

If you are not on the command line, you might use [ALT]+[F2] to run a command... and the same commands would work that way, too.

Answer 3

I had this problem and was doing tasks with USB pendrives until now, erroneously thinking it was a software problem...but today I just used a extended paperclip to open the CD/DVD tray using that little hole under the tray on the unit panel...after THAT the tray begun responding to commands via software or hard button...

So I think this was a hardware little lock (after moving around the pc) or a rubber belt out of place due to wear and tear...as concluded by another contributor here in this site...

Just my experience.

Cheers and thanks.
