Some (k)ubuntu and Thunderbird questions

[Evan Leibovitch]

Hi folks.

Moving over from Mandriva to Kubuntu Edgy, I still have some lingering
questions about the packaging system (adept, apt-get, dpkg, etc.); any
help is appreciated:

1) What is the dpkg/apt-get equivalent of `rpm -qf filename`, which
tells you the name of the package that `filename` belongs to? Can this
be searched in any of the GUI tools?

2) Similarly, how can I query the database of uninstalled packages to
ask what package would need to be installed to give me a specific file?
(This query was brought on by the earlier question of where to find
"smbmount" when that is the name of a command embedded inside a package
of another name. How do I ask adept or apt, "what package, if installed,
would provide the file named `smbmount`"?)

3) In Mandriva, when the notification system said there were new package
versions to download, it would tell me whether the need for the upgrade
was critical (ie, security or sever bugfix) as opposed to low-priority
(cleanup or feature-add). I was able to look at the GUI package manager
and get a full changelog. In `adept` I can't seem to find anything to
show me this info in either `adept` or `adept_updater`. Am I missing
something?

I also have two non-packaging questions, both related to the Kubuntu
package of Thunderbird (rel 1.5.0.7):

4) The little application icon in the upper left corner of the window is
the generic "X" logo as opposed to an applications icon. How/where can I
change this? All other apps (including Firefox) seem to have this down OK.

5) When I click on a link in Thunderbird it calls Konqueror to open the
page, not Firefox. This is doubly weird, considering that I've changed
the KDE settings properly -- when I click on a link from Kmail it calls
up Firefox, but when I click a link in Thunderbird it still goes to
Konq. I have no idea of how to set things within Thunderbird to change this.

and finally:

6) How can I remove something from the Kicker? I accidentally installed
a keyboard-changing applet, and I can't seem to remove it. I need to
close it every time the system boots, and I can't seem to find out where
I can manually revove stuff from the KDE panel such as the OpenOffice
quickstarter, etc.

Again, thanks for any suggestions.
