If you use the GDM login manager you can su to root (type
su in a terminal and then the password when asked; type
exit when you're done doing whatever it is you wanted to do and become your old boring self again), then run
gdmconfig. It may also be called
gdmsetup (or is it
gdm-setup?) in some versions. In this graphical configuration program you can choose your options. I do however recommend that you do NOT allow root to log in using GDM. There is absolutely no reason to ever run X as root. Whenever you need root privileges, use the
su command, or Alt+Ctrl+F1 (any virtual terminal from F1 to F6) and log in as root there. You can then switch back to the graphical user interface with Ctrl+Alt+F7.
Debian doesn't ship pine as a binary because of license problems. You can build it from source, use
mutt (a lesser email client), or add this line to /etc/apt/sources.list and do an
apt-get install pine:
dselect is pretty straight-forward and efficient once you get used to it. If you want to mark a package for installation in the package listing, just hit the + key on your keyboard. The minus key removes packages (be careful, you might remove more than you thought you would becasue of dependency problems!). When done, just hit return until you return to the main screen, and hit Install....follow the instructions basically.
