Then have a look at your your '/var/log/Xorg.0.log'. You will find a

Nope. Already tried that, and the capabilities were /not/ listed in the log,
the way it was described in several tutorials.
<rant>This is starting to look like one of the most common problems in
F/OSS: Theory != Practice. In theory, any one of the methods already tried
and suggested here should work. In practice, the "documentation"
(MonitorsDB) is wrong (at least according to x.org), and none of the quoted
methods work the way they should. An interesting result is that there are
several fundamentally different tutorials for several closely related
*nixes, all of which work only on a small subset of installations.</rant>
