CD/DVD change not recognized

[kallewirsch]

Binary package hint: udisks

If I insert a disk into my CD/DVD drive, nothing happens (not shown on desktop, rythmbox, no traces in syslog). udisks --monitor-detail shows nothing, although udisks --enumerate / --show-info and dmesg show the drive properly.
If I however issue udisks --poll-for-media /dev/hdb after disk insertion, the disk appears as if by magic.

This affects at least all powerpc installations (see http://ubuntuforums.org/showthread.php?t=1323153 and https://bugs.launchpad.net/ubuntu/+source/gnome-mount/+bug/507113).

Bug confirmed on an iBook G4. Udisk polling fix also works, but this make PowerPC utterly broken for people who aren't comfortable with terminal.

[Jason Ritzke (sha-goyjo)]

Sorry, forgot to add that it's the 1.3 Ghz 12 inch iBook G4

[J. McDonald (mcdonald-joseph)]

Confirmed on a "windtunnel" G4 (dual 1.42 Ghz). As in the example above, I can manually poll with:
     udisks --poll-for-media /dev/<devicename>
and the media is immediately recognized. Oddly, I only have problems with the internal ATAPI Pioneer DVR-105 DVD/CD/RW. If I plug in an external USB DVD/CD/RW drive and place media in the drive, it automatically polls the media and works fine.

[J. McDonald (mcdonald-joseph)]

For me, doing:
     eject -T && udisks --poll-for-media /dev/hde

from the terminal gives the desired behavior. The problem is that I am too new to Linux to figure out a way to bind that command to the Apple keyboard "eject" key (which I think is key #161).

[J. McDonald (mcdonald-joseph)]

I ended up writing a very simple shell script to load or eject CDs and poll udisks, and then I call the script from a Gnome panel custom application launcher. It's not ideal, but it works for me until udisks is fixed.

[J. McDonald (mcdonald-joseph)]

This may be some sort of problem in the powerpc 2.6.32-xx kernel. See here:
http://ubuntuforums.org/showpost.php?p=9505509&postcount=21
Has anyone tried compiling a 2.6.34 kernel for the Ubuntu 10.04 powerpc port? If so, did that fix this problem?

[J. McDonald (mcdonald-joseph)]

also check here:
http://www.ppcnux.com/?q=linux-kernel-2.6.34-with-ubuntu-10.04

[J. McDonald (mcdonald-joseph)]

I recently upgraded to the the following kernel:
Linux G4 2.6.32-24-powerpc-smp #39-Ubuntu SMP
The CD/DVD bug is still there.

Same problem on an iMac G5.

[Jochen Fahrner (jofa)]

I did some more testing. An external USB DVD writer (Samsung) is working with no problems. Inserted discs are immediately recognized.
The internal drive does not recognize inserted discs. The command "udisks --poll-for-media /dev/cdrom" makes them available and they are automounted.

[Bodo Hoffmann (pebkac)]

Same thing here on my PowerMac G4 450Mhz AGP.

Another feature is:
When I'm logged in, it's difficult to insert a cd/dvd into the drive, because the door will be closed immediately,
when I press the push-button to open the door (less 1 sec).
Before I log in, the door stays open as long I press the eject-button again.

[Antonis Christofides (anthony-itia)]

Except for the problems already mentioned, in my ibook g4 the device file has group disk instead of cdrom. I think that part of the problems may be because of the name "hdc" that is assigned (by the kernel I guess) to the cdrom, whereas udev and other subsystems probably expect it to be named "sr0" or something.

Status changed to 'Confirmed' because the bug affects multiple users.
