Comment 27 for bug 438065

Folks, this issue is almost fixed.

Look at,

https://bugs.launchpad.net/ubuntu/+source/devicekit-disks/+bug/397734

There are two problems.

First is that brasero nautilus plugin was locking the DVD drive. This one and many many more bugs were fixed in the git branch 'gnome-2.28' in the brasero git repository.

Another problem is that devkit doesn't poll the drive to see if user have pressed that eject button, however the kernel by default tells the drive to lock the button, so it doesn't eject the disk.
It was agreed that we need to change the kernel not to lock the drive.
This can be meanwhile done by issuing the:

echo 0 > /proc/sys/dev/cdrom/lock

(This will take effect when new disk is inserted)
