Witam,
czy komuś z was udało się może osiągnąć takie połączenie (jak w tytule)? Tzn. chciałbym wyświetlać ten sam obraz na monitorze zewnętrznym jak i na matrycy laptopa (widescreen). Mi się to udało, ale rozdzielczość monitora jest taka sama jak na laptopie (czyli wyświetlany obraz jest rozszerzony w pionie).
Gdyby można było ustawić wyświetlanie obrazu z rozdzielczością natywną dla monitora zewnętrznego LCD (obraz mógłby być przeskalowany i np. po przesunięciu myszką z lewej czy prawej strony ekranu mógłbym uzyskać dostęp do całej wyświetlanej "powierzchni" albo ze względu na tą samą poziomą składową rozdzielczości obraz wyświetlany na monitorze LCD można by było przyciąć w pionie i uzyskać efekt podobny jak w przypadku filmów).
Docelowo jednak chciałbym uzyskać taką konfigurację xorga, żebym mógł utworzyć dwa display-e. Żebym jeden mógł obserwować na zewnętrznym projektorze i pokazywać np. jakąś prezentację, a na drugim mieć jakiś tekst (np. komentarz).
Jak ustawię opcję "DefaultServerLayout" jako "Single" w sekcji "ServerFlags", to wszystko chodzi. Jak przestawię na "Dual" to już nie.
Oto kilka plików konfiguracyjnych i takich tam:
