i810 im Dualhead-Betrieb

[Cypher666]

Ich versuche verzweifelt einen externen Monitor an mein Notebook anzuschließen.
Bekomme aber folgende Xorg Fehler:

(EE) I810(0): You must have a MonitorLayout defined for use in a DualHead or Clone setup.
(EE) I810(1): Failed to setup second head due to primary head failure.
(EE) Screen(s) found, but none have a usable configuration.

meine xorg.conf sieht folgendermaßen aus:
