Hallo,
ich besitze ein Dell XPS 13" Ultrabook, welches ja nun offiziell von Dell mit Ubuntu angepriesen wird. Innen drin ist eine Intel GMA 3000 und als Ausgang gibt es einen Mini Display Port. Soweit auch alles toll.
Wenn ich nun mein Apple Cinema Display daran anschließe dann funktioniert es manchmal, meistens jedoch nicht. Ich kann auch absolut nicht feststellen wieso und vorallen wann es funktioniert. Es geschiet vollkommen willkürlich. Egal ob Strom angeschlossen oder nicht. Egal ob Montag oder Mittwoch. Egal ob grade frisch gerebootet oder nicht.
die X Log ist leider wenig aussagekräftig:

Das ist alles. Vorallen die letzte Zeile sieht echt merkwürdig aus.
Falls fragen sind, immer her damit. Das Problem geht mir aber echt auf den Zeiger...
