Risoluzione schermo

[MinaVagante]

Ciao a tutti,
ho appena installato da zero ubuntu 9.04 su un pc fisso, ma ho dei problemi riguardo la risoluzione dello schermo, che risulta essere non superiore a 800x600. Inoltre quando apro qualche programma i bordi o qualche porzione di finestra esce dallo schermo.
Ho una nvidia geforce fx5500, e ho già installato i driver raccomandati 173, ma in nvidia-settings non posso impostare una risoluzione maggiore a quella precedentemente indicata.
Vi posto il mio xorg

Grazie
