<pre wrap="">From what I recall (I believe I have this board on my desk somewhere),
this board is actually two separate GPUs, each one driving two
outputs. Your best bet is to treat it as one would an "Optimus"

<pre wrap="">Thank you Ben, for the hint.
Unfortunately I am trapped by another problem: after switching back from
NVidia driver to Nouveau driver in Ubuntu, I get GPU lockups already at
boot time, rendering the system inaccessible. This is a peculiarity of
the combination of my mainboard and NVidia graphics card. I already
filed that issue to the Ubuntu bug tracker. Booting with
nouveau.noaccel=1 works but KDE crashes silently during initialization.
I thus had no chance to try the Optimus thing at all. Deadlocked <span class="moz-smiley-s2" title=":-("></span>
