1) Since you get the login screen, X has to be working. Presumably,
that's with full root permissions.
2) When you try to login, screen blanks and eventually returns to the ?DM
login screen. Of course, in the process of logging in as your user and
getting a kde or twm session, you'll switch to user privs for some
things. That this doesn't work but the login screen as root does, hints
at a permission issue, or an issue setting up the user "magic cookies"
that allow an ordinary user to access the xorg server running as root.
3) That begs the question , what happens if you create a fresh user and
try to login as them, and/or if you try logging in as root? (Yes, I don't
recommend it for normal usage either, but for testing... disconnect from
the net if you're paranoid, backup your /root so you can restore it to pre-
X-login condition afterward, and try the root thing.) If a new/clean user
works, then you know it's something in the user config. If it doesn't but
root works, you know it's a permissions issue of some sort.
4) Due to ?DM breaking on me years ago on Mandrake, I quit using ?DM
graphical logins then, and have never gone back, choosing instead to login
at the text console and startx as my preferred user. You mention nothing
about even trying that. Does /that/ work and you simply prefer the
graphical login, does that not work either, or were you unaware of the
Obviously if it works you have a workaround. At least that way you can
run your graphical environment of choice, even if you don't like the login
method. Plus, the results of this test should help someone a bit more
skilled in ?DM technologies than I am (as I said I quit DMs long ago)
figure out what's going on.
 Literal/descriptive usage: Greek or Latin logical fallacies aside,
the intent here is the literal meaning of the English words: The lead-up
now begs that the question be asked.
