xorg does not display these by default. xorg does NOTHING by default. all of
this stuff is done by your login session apps like the window manager and so
on. you've gotten past your issue. the xserver works. it worked before (just
was black). xorg, its rendering, drivers, input work. you have a terminal. you
can type in it. you want to start a whole x SESSION. that's what things like
startx, xdm, gdm, kdm, slim, lightdm, etc. etc. etc. do - they do all of this
and go launch everything (and in the case of all by startx also handle logging
in a specific user and authenticating them if needed).

this is what all those desktops - enlightenment, gnome, kde, xfce do. they
provide all the thing you CALL an xorg desktop. each is its own project. you
want to run one of those in your login session. as above - these tools
generally would do that for you. they may use your ~/.xsession script to decide
what to do or ~/.xinitrc or provide a gui to select a session. you would need
something installed.

you could install more basic window manages with far less stuff  like twm.
fvwm, etc. etc. too... but you will want something else than just xorg. xorg is
basically a driver with an ipc/network front end that apps talk to to do the
rest.
