There's a number of things:
-- you seem to be logging into your X environment as root.
This is not a particularly good idea. Much better to
create yourself a normal user account for that, and use
su(1) or sudo(1) to take rootly powers as required.
-- You don't say what sort of graphics card the system has.
If you look at /var/log/Xorg.log.0 (or something similar to
that) it will have that information amongst a lot of other
stuff.
The nature of the graphics card is important, because some
models don't switch back to console mode from graphics mode
very well. It's a known bug, and unfortunately if you have
one of those models the best advice at the moment is to run
a display manager (xdm, kdm, slim) and always use a graphical
login.
-- The use of 'exec' in ~/.startx is correct, but not if you're
typing that from the shell command prompt. What exec does is
*replace* the current process with the one you called. That's
fine if you're replacing the (very small) shell script that is
~/.startx, but not if you're replacing your login shell.
The recommended way to start X from the command line is to set up
a ~/.startx script (which could contain just your 'exec
gdm-session' command, or quite a bit more. Then type startx to
(like it says on the tin...) start X.
Cheers,
Matthew
