Bug Description


On my laptop, pressing the hardware "eject" button on the DVD drive will pop out the disc, but it will still be treated as mounted by Nautilus. If I then put in another disc, it will still think that the files from the previous disc are there, as though it had not been ejected. This produces an error when I try to manipulate those files.

I can't access the files from the new disc until I eject the old one using the button on Nautilus.


1. Put a CD or DVD in the drive, close it, and let Nautilus mount it.
2. Eject it using the hardware eject key.
3. Put in a new CD or DVD.


Nautilus will know when I ejected a disc.

Confirmed on precise on my laptop, some infos:
- the disk stay in the ui
- the directory is still in /media and I can still ls it without issue after ejecting the disk
- udisks --dump lists the disk as mounted still

Martin, do you have any clue if that's udisks, udev or the kernel to blame?

The first reason is that our current kernel package seems to have the "block" module built in now, so the udev rule which is meant to set the default in-kernel polling value doesn't work:

ACTION=="add", SUBSYSTEM=="module", KERNEL=="block", ATTR{parameters/events_dfl_poll_msecs}=="0", ATTR{parameters/events_dfl_poll_msecs}="2000"

This requires a sysctl.d setting now. Will add to udev package.

However, even when I set the polling interval manually, the kernel still doesn't emit an eject_request uevent, even though it claims to:

$ cat /sys/block/sr0/events
media_change eject_request

I still need to investigate that.

This bug was fixed in the package udev - 175-0ubuntu4

udev (175-0ubuntu4) precise; urgency=low

  * Add builtin-block-polling.patch: Set default polling interval on CD drives
    as well. The events_dfl_poll_msecs will not trigger if "block" is not a
    module, but built in. This will avoid udisks etc. having to poll from
    userspace, and provide proper ejection when the hardware eject button is
    pressed. (LP: #890592)
  * Add 00git-keymaps.patch: Backport keymaps from current git master.
    (LP: #901513, #902332, #902798, #914838, #922405)

The second half of the bug is that the kernel does not send an EJECT_REQUEST uevent any more when the hardware button is pressed. That definitively used to work in the past, but apparently something changed. I'll have a closer look at this.

I use xubuntu 12.04 with 3.5.0-22 kernel

$ uname -a
Linux Acer 3.5.0-22-generic #34~precise1-Ubuntu SMP Wed Jan 9 21:45:40 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

I found that kernel polling does not work with some optical drives, even if I do:
echo 2000 > /sys/block/sr?/events_poll_msecs
echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs

I can't eject my embedded notebook drive (ID_SERIAL=HL-DT-STDVDRAM_GT31N_KZLAC5D2847) with eject button, but eject /dev/sr0 is working, and eject -i 0 /dev/sr0 is working to.
And no udev events is generated while pressing eject button.

I test this with external USB drive to (ID_SERIAL=TS8XDVDR_Transcend_613143333435363738394B4C-0:0).
But with this drive eject button is working, and udev events is generated.

Ok, but I found more. With those external USB drive eject button stops working while disk is mounted. And while disk is mounted udev receive no eject event from drive eject button. But if I unmount disk by hands after pressing drive eject button, drive ejects itself (and udev receive change event). Seems like while disk is mounted, kernel eject event is waits in some kind of queue.

For workaround I was trying to restore udisks polling (11.04 behavior) writing some udev rules to set ATTR{events_poll_msecs}="-1" and disable tray locking on my devices. It's working, udisks polling is enabled, but again while disk is mounted I can eject it with drive eject button, but no udisks/udev events is generated, and no unmount is performed, I have to unmount it manually.

I even cannot enable old udisks behavior that was working fine for me in 11.04.

Fix it please! Two years is passed.

As a temporary workaround I installed udisks_1.0.2-4ubuntu2_amd64.deb from
and disabled cdrom tray locking/kernel polling in udev rules.
And now it is work fine, like was in 11.04. Eject button is ejecting and udisks-daemon is auto unmounting disk after eject.

Ain't working normally in Ubuntu quantal (12.10) too!

tested on:
Optiarc DVD RW AD-7560A

When I'm inserting or ejecting disc, I can see events:

$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

But, when the disc is getting mounted, I can't nor eject it with drive's eject button nor see events:

$ udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Nothing! Silence!

I've tryed also with latest kernel from ppa. No changes.

Hello. I can also confirm this on ubuntu 13.10.

When I put in a dvd (The Avengers for example) it is mounted as - /media/ukbeast/MARVELS_THE_AVENGERS
when I press eject on my ata-Slimtype_DVD_A_DS8A8SH_3208583_632219412703 dvd ejects but the dvd is still mounted as

I find it annoying because I use leawo bluray player for my dvds using wine beacuse the sound seems better than VLC and I have to close and open the software to unmount the dvd in nautilus, so that wine can pass the mount information to leawo.

I can confirm this bug still exists in 13.10.

On my current machine, it has existed for years now, but it does not seem to be a problem on other machines I have.

Maybe this is an old broken setting that is never deleted during upgrades? (I haven't done a reinstall since 10.04, only upgrades).
Could there be a way to tell the system to "re-configure" the cdrom drive to get rid of this behaviour?
