device issues with 'hald'

Hello,

Upgraded to kde 4.3.2 (by upgrading kubuntu from 9.04 to 9.10). All
works fine except for serious issue, namely that no device seems be
taken into account. I have no feedback from device notifier, I
cannot see them inside Dolphin. when I tey to "open" from device
notifier (predefined action), nothing happens, Dolphin does not even
start, no error. The same issue applies to:
* usb memory sticks (both at front back of computer)
* internal CD drive (with data CD inside)
* extrenal CD drive through usb port (ditto)
* EDIT: also tried audio CD without success
But there is a difference between memory sticks & CDs (see below). 

I found some possibly related threads at
http://forum.kde.org/viewtopic.php?f=67&t=62449 and
http://forums.freebsd.org/showthread.php?t=5672, and also
http://forum.kde.org/viewtopic.php?f=66&t=82975&start=0. Tried to
follow approaches described there:
* Get feedback from 'dmesg'.
* Check 'hald' runs.
* Check PolicyKit config
* Get info from 'solid-hardware'.
* "Manually" enable devices.
See console output copies below for detailed results of these
actions.


Summary of trials:

* dmesg shows feedback when usb sticks are plugged, nothing about
  CDs. Why, I cannot guess?

* There is an issue about hal and solid, or rather they do not seem
  to understand each other. Seems to be rather on hald's side, for
  even if hald runs I cannot execute 'lshal'; output: spir at o:~$
  lshal Could not initialise connection to hald. Normally this means
  the HAL daemon (hald) is not running or not ready.

* There is nothing at all about hal in System Settings/PolicyKit
  (only about PolicyKit itself, PackageKit and k3b). PolicyKit.conf
  seems to be default (should work as is?). Anyway, the issue when
  solid requests info does not look like related to authorisations.
  I tried anyway to add the following lines about device management,
  as proposed in thread #2: <match
  action="org.freedesktop.hal.storage.mount-removable"> <return
  result="yes"/> </match> <match
  action="org.freedesktop.hal.storage.eject"> <return result="yes"/>
  </match> <match action="org.freedesktop.hal.storage.mount-fixed">
  <return result="yes"/> </match>
There was no change, so I reverted the modif.

* I also tried (found on another thread):
    spir at o:/media/cdrom0$ hal-disable-polling --enable
  --device /dev/cdrom Could not initialise connection to hald.
    Normally this means the HAL daemon (hald) is not running or not
  ready.

* Finally, I found 'hal-info' installed, according to KPackageKit,
  but: spir at o:/media/cdrom0$ hal-info
  No command 'hal-info' found, did you mean:
  Command 'al-info' from package 'flightgear' (universe)
  hal-info: command not found

Can someone help me with this issue? It is especially ennoying now
because, having just upgraded, all my personal data are saved on
CDs and usb memory sticks.

Thank you,
Denis
