I would like to restore LightDM to its default state, because for some reason
/etc/lightdm/unity-greeter.conf is now an empty file.
Deleting /etc/lightdm/unity-greeter.conf and then running sudo apt-get install --reinstall unity-greeter doesn't create a new config file as you might expect.
How can I restore a missing config file?
I would like to use a gesture to shutdown/restart my computer and I need to know the command that launches the shutdown dialog:
Every key in the DConf database has a default value that is used when user accounts are created. How can I change these default values?
When I try to install updates (via either Update Manager or apt-get upgrade) the usual apt upgrade process is stopped as it shows me some changelogs, for example:
Nothing will happen until I hit the q key, then it outputs:
apt-listchanges: Mailing root: apt-listchanges: changelogs for msg
(msg is my hostname)
and finishes installing the updates as usual. This doesn't happen when installing a new package, only when installing updates.
What is causing this? How can I fix it?
I am downloading a very large package and my internet connection isn't the fastest, so browsing the web at the same time is a pain. How can I limit the bandwidth apt-get uses?

I accidentally unchecked View -> Show Menubar which hides the menubar for gnome-terminal, and there doesn't appear to be a keyboard shortcut to show the menubar again.
How can I make gnome-terminal show the menubar again?
There was recently another release of LibreOffice, but it is a pain to have to manually go to their website and download the packages every time there is a new release. Is there a PPA that always has the latest version of LibreOffice?
On Launchpad.net, most projects list the programming language(s) their software uses:
It would be useful if there was a way to get a list of all the projects that use "X" programming language, in my case Vala. Does Launchpad provide this functionality? Are there any 3rd party tools that can do this?
Is there any software or website that allows the user to view a graph of how popular a particular package is? The popcon.ubuntu.com site has raw information on how many people
(who have installed popularity-contest) have installed a particular package, but it would be interesting to see how a package's popularity changes over time.
I remember using a website that graphed this, but I don't know if it still exist.
I recently installed Synapse and I noticed there is an Internet category on the far right, but there it doesn't return any results. What do I need to do to enable it to search my web browsing history? I am using Google Chrome.
The only documentation I have been able to find on integrating an application with the Messaging Menu is old and out of date: http://gnomejournal.org/article/67/an-introduction-to-the-message-indicator. And even that didn't have documentation for the whole API. Is there are any documentation for libindicate, either the python or C version?
Is there a faster way to print multiple ODT documents besides opening each one in OpenOffice/LibreOffice and printing each document separately? It would be great if I could just select multiple documents in Nautilus and have some option to print them all with the same print settings.
Sometimes when there are too many users logged in it can cause my computer to become very slow and laggy due to low amount of available RAM. I would like to be able to quickly log out the other users from the command line instead of manually switching into each user and logging them out.
Is this possible?
I was trying out Unity and then I uninstalled it but there is still an Ubuntu Netbook Edition option in the GDM session list. Accidentally clicking on that causes the user to log in to a broken desktop. How can I remove it from the list?

I would like to organize all the music files in ~/Music in folders by their metadata.
So the directory structure would look like this:

Song.mp3
Is there a tool for this purpose?
