help!!! vorrei riuscire a utilizzare i driver vesa con risoluzione 1280x800 o 1280x768, come riesco con i driver fglrx (questi non li voglio usare per provare l'ultima versione di metacity con composite integrato, e con gli fglrx non va per niente bene) però non riesco a cambiare nulla!
ho dato un dpkg reconfigure e questo ora il mio xorg.conf
