Is it possible to add a feature to open a dvd-lw

... with the drive-button?

I've 3 drives in my paldo-machine. One DVD-LW, one CD-RW and one DVD-RW.
When I have a disc mounted in the CD-RW/DVD-RW it will be unmounted by pressing the eject-button on the drive.

The DVD-LW can only unmount a disc by using the normal unmount-way.

Is there a way to unmount it also with the button on the drive?

btw. in KDE it works ...

What do you mean with DVD-LW, a DVD-ROM drive? If the hardware eject button doesn't work, it's usually a hardware limitation, especially if it works with other drives in the same system. Are you sure that it worked with the same drive in KDE?

Yes, cos I tried it with KDE 3.5.5 in different distributions. Only RW-drives you can eject in gnome using the hardware-button, but not readonly-drives.

So my thought was to fake the readonly-drive to a RW-drive to check if it works also under gnome this way.

If you want to try it yourself download a live-cd with kde on it and put a dvd/cd in your readonly-drive. You can eject it by pressing the hardware-button. Shure, you must have two drives in your machine to test it this way.

I don't have a read-only drive at hand right now but it'd be a pretty strange bug if it just doesn't work with read-only drives. The read-only drive is possibly older, so it might not be MMC compliant (or not to the same level) as your RW-drives.

Follow these steps to find out where the problem lies:

Insert a disc into your read-only drive
Start "lshal --monitor" in a terminal
Press the hardware eject button

You should see something like

Zitat

storage_model_DVD_RW_ND_3540A condition EjectPressed

in the terminal. If you do see the message, it's a gnome-volume-manager or gnome-mount bug; if you don't see the message, it's a HAL, Linux, or hardware issue.

I insert and removed some cd/dvds. Only the readonly-drive dosn't react by pressing the hw-eject-button.

Ok, when you say the same drive works on other distributions, it's probably a Linux or HAL issue. Could you try in stable or testing if you've previously tested in unstable to check whether it's a libata issue? The kernel in unstable uses libata for PATA and SATA controllers, the kernel in stable and testing uses the older ide layer for PATA controllers.

It works only in KDE but NOT in Gnome.

Thats a post of mine in the german Ubuntu forum. Seems it has something to do with my drive.

It surely wouldn't work in KDE on paldo, as your test showed that the problem lies on a lower level, i.e. HAL doesn't get notified. There is nothing GNOME can do about that.

BTW: The tests you've done in other distros with KDE were done with the exact same drive, not just with another read-only drive, right?

Yes I did it with the exact same drive. Seems KDE handle it different than gnome. I'll do again a test with Kubuntu 6.06.1 LiveCD and some other distros. Maybe I can monitor something.

I did this by pressing the eject-button on the readonly-drive running the liveCD of Kubuntu 6.06.1.

And this is the kernel version:
