Problem with Display After Installing SUSE 11.1

[philipanish]

Hi,
I have installed SUSE 11.1 and by default it selected a resolution of "1440x900", now as a result X crashes or won't start up. Below is the extract of my xorg.conf file , please suggest the changes that i need to make to the parameters below. Will Changing the PreferredMode to "1024x768" reolve the problem ? or should i change the driver to "vesa" ?

Did you download and install drivers. I'm not sure how well supported your device is, but it is shown in the list here: Graphics Drivers & Software

Have you tried booting Failsafe for now, until you sort the driver out.
