Gnome

Always when I logged into a Gnome session, automatically several application started up without me wanting them to start up (two terminal sessions and a nautilus windows). To get rid of them (at least I think so, I will see at the next login), you have to go to Main Menu - Preferences - More preferences - Sessions. Under the "Current Session" tab, one can remove the programs that are automatically started upon login and also specify in which order the programs are started that are started automatically.

The files that specify the different folders and buttons of the Gnome user interface are somehow really badly distributed all over the place. Here are just a few of the more common locations:

Icons in the panel: ~/.gnome2/panel2.d/default/launchers/
Contents of Start Here: ~/.gnome2/vfolders/start-here/
user's Home, Trash and Start Here: ~/.gnome-desktop/

I have installed the Staden package on my laptop. In order to convince other people from my lab to use it, it must be very easy to use. Ideally, they should just need to select some sequences, click and the preprocessing and assembly should be done automatically. In order to achieve that I did the following: I created new mime types for the file manager Konqueror. Konqueror needs this to realize what it should do with a file (or several of them) when you click on them. Go to: Start Menu -> Control center -> KDE Components -> File Associations.
