nastavení WXGA 1280x768 TFT

Potřeboval bych poradit. Mám na notebooku TFT display který á nativní rozlišení 1280x768. Toto rozlišení jsem nastavil v X ( xorg-X11 v. 6.9 ). Problém je, že pokud na tento display nastavím rozlišení 1280x768, nastaví se rozlišení 1024x768 a rozlišení 1280x768 je pouze virtuální a tedy pomocí myši mohu vodorovně scrollovat. Což mi tedy vůbec nevyhovuje a nevím jak mám donutit X aby použily to rozlišeí jako reálné. Display se pomocí Plug and play nedetekuje. Toto je konfigurák z xorg.conf. Byl bych vděšný za radu. Díky ...
