You need to install xorg and the windowing system and synaptic.
Log in as normal user. Type su to go to the root account.
Type in "apt-get -y install xorg synaptic". If it asks for the install cd, insert it. After the install is finished, exit from root and type "startx".
Right click on the screen and a term should come up.
Type su then type synaptic.
Use the tools to search for the desktop.
Or, do you know which desktop environment you want? There are four main available ones: kde, gnome, xfce, lxde.
If you know which you want then you can start such as this:
when you log in as the initial user, su to root- this means type su then hit enter then type in the root password when it asks- type in the following command: "apt-get -y install xorg <the desktop environment you want> synaptic" hit enter. Let it finish. Log out of root- type exit- and then type startx.
You are going to look for synaptic and you are going to install the sound system along with web browsing.
In kde the menu is at the bottom left such as in windows. click the K once, go to system, choose synaptic. Type in the root password whhen it asks. Be sure to leave or make the remember root unchecked.
Run the mouse over the all then click on search. Type in alsa and hit enter. You will mark alsa, alsautils, the alsa gui. Next search for esound and choose the pulse audio interface. Next install pulse, pavumeter and a few other tools. Search next for iceweasel you can add support for our native language if it isn't english. and then for noscript. Noscript will be a mozilla addon. I suggest that you use it . Click on the settings menu, go to repositories and uncheck the cd. hit exit to save.
Once you have the packages that you want, hit the green check/install and hit yes/agree/confirm when it comes up. When everything is installed, you can close the window.
The same for gnome but that it is at the top and under the settings menu.
Xfce: right click anywhere and go to system then to synaptic.
Lxde: similar to kde, right hand bottom corner.
This should get you started.
Go to the debian forums, join, and do the following.
Use the search, type in the basic idea of what you want, and choose the document/howto section.
This will get you started.
