New installation - cannot increase the screen resolution

[Chan Lee <chanl@pacbell.net>]

Hi,

 

I just installed Debian using DVD set from CheapBytes

into a new HP Pavilion Slimline s3020n desktop. It has

Nvidia GeForce 6150LE graphics adaptor driving 1280x1024

resolution.

 

Thrying to increase the screen resolution using the Screen

resoultion preference tool, however, I cannot find any extra

resolution option in the menu - only the basic resolution of

640x480 is available. The Samsung 19inch LCD screen can

display 1280x1024 - how can I increase it ?

 

Thanks for your help in advance,

 

Chan
