Salve a tutti, ho un problema che definirei demoniaco.
Ho un portatile acer aspire 5024 con scheda video ati mobility x700.
Ieri ho provato a configurare con sax2 la modalità dualhead, ma siccome avevo modificato manualmente il file xorg.conf la procedura non è andata a buon fine.
Ho provato con aticonfig e il nuovo file xorg. conf non funzionava.
Allora ripristino il vecchio xorg che diligentemente avevo messo da parte, riavvio e cosa succede? Praticamente che il monitor esterno sia collegato o meno mi ritrovo con gdm (uso gnome) che parte in modalità 2560x800 invece che 1280x800. Una volta loggato mi tocca cliccare sull'icona della risoluzione nel system tray e selezionare 1280x800.

Adesso vi posto il mio xorg.conf:

Io non vedo nessun riferimento a 2560x800! Da dove prende gdm questa risoluzione!
Inoltre non è che lo schermo è deformato....è proprio come se il desktop fosse esteso su uno schermo che però non è collegato!
Ho provato anche a concellare xorg.conf, andare in init 3 ed eseguire nuovamente sax2. E anche in tale occasione, quando faccio la prova della configurazione mi appaiono due finestre di regolazione: una per display 0 e una per display 1, anche se poi in yast-->scheda video e monitor vedo solo un display.
Ho controllato anche le opzioni del bios, ma l'unica opzione per il dual monitor non ha effetti su questo maledetto problema.
Qualcuno ha idea di dove possa stare il problema?
Grazie e mi scuso per la lunghezza del post.
