Meine Erfahrungen beim Konfigurieren eines externen Monitors an einem Dell Inspiron 9200 möchte ich hier kurz beschreiben. Ich habe dabei nur versucht den analogen Ausgang zu konfigurieren, nicht den DVI-Ausgang mangels geeignetem Endgerät.

Auf dem Rechner kommt XOrg in der Version 6.8.2-r1 mit den vorkompilierten ATI-Treibern media-video/ati-drivers 8.14.13-r2 und die media-video/ati-drivers-extra 8.14.13.

Mittels dem Tool fglrxconfig aus dem ati-drivers-extra habe ich mir eine Funktionierende Xorg.conf zusammengestellt, vorwiegend mit den Standard-Einstellungen. Danach habe ich die Einstellungen entsprechend den speziellen Bedürfnissen angepasst.

Zu beachten sind dabei folgende Punkte:

Leider scheint nur die gespiegelte Ausgabe, bei der auf dem externen Monitor das gleiche zu sehen ist, wie auf dem eingebauten Display, zu funktionieren. Die anderen Einstellungen lassen den X-Server nicht mehr starten.

Noch ein Tipp: das X-Tool fireglcontrol kann zum einstellen des Displays benutzt werden, es kann die Ausgabe gesteuert werden wie nur internen Monitor, das gleiche auf internem wie externem Monitor ausgeben und extended-Desktop Einstellungen. Es verändert jedoch direkt die xorg.conf ohne ein Backup davon zu erstellen. Ein Backup vor Gebrauch des Tools von der /etc/X11/xorg.conf ist also dringend anzuraten.

Hier die komplette xorg.conf:
