User:Skierpage/CD drive woes

Kubuntu 11.04 was working fine in one AMD64-bit PC. I swapped my hard drive into another PC, HP Pavilion a1012x, and it booted right up and everything works fine! Except... on the new PC no Device Actions trigger when I insert a data CD, music CD, or DVD into either of its CD-ROM drives.

I don't get the "Available Devices" menu of options to Open with File Manager/VLC /Dragon, and the USB icon says "No Devices Available". I have the usual rules for this in System Settings > Device Actions, but they don't fire.

Works

A music CD shows up fine in dolphin, device action "kioclient exec audiocd:/" works fine, vlc can File > Open Disk > /dev/cdrom1" fine...

Inserting a USB flash drive makes "Available Devices" appear with option to mount it.

Tried

I tried system settings -> removable devices > enable automatic mounting of removable media, didn't help

Solid!

Maybe some hardware didn't get reconfigured.

The problem seems to be in the Solid layer.

Solid knows there's an Audio Optical Disc plugged in, but it's ignored, and the System Settings > Device Actions rules include "The devices Ignored must equal false".

How do I tell Solid not to ignore the storage volume?!

udisks

Solid is probably (?) talking to udisks, I have a process

udisks-daemon: polling /dev/sr1 /dev/sdg /dev/sdd /dev/sdc /dev/sdf /dev/sde /dev/sr0

I ran udisks --monitor-detail and when I inserted a music CD I got

Bugs

This sounds similar to Launchpad bug 709868 "kde 4.6 device actions broken".

He has the StorageVolume.ignored = true. He comments

Ok... experimented a bit about how solid-hardware works and found what the latest problem is

One needs to create /media/cdrom0 by hand.

Solid does not manage mount points automatically creating dirs in media at need

Solid does not anymore mount by label... namely should have mounted as /media/CDSTOMPER35 but mounts as /media/cdrom0

But I have a /media/cdrom symlinks to /media/cdrom0 , so that's not it. I have /dev/cdrom1 and cdrom2 symlinking to /dev/sr0 and /dev/sr1. Do I need to create a /media/cdrom1 ?

I filed KDE Bug 280229 "Device Actions don't trigger for my CD-ROM drives, StorageVolume.ignored"

Another bug TODO: none of the links on solid.kde.org work, they just redirect to the home page.

Other

System Settings > Multimedia > Audio CDs > General > Specify CD Device is /dev/cdrom. I don't have this, I have /dev/cdrom1 and /dev/cdrom2. Should I change this or is it another bug that this is wrong?
