I have an old Inspiron 6400. I want to be able to extend/duplicate my display over to another monitor, but am unable to do so. I can use either of the monitors when I activate CRT/LCD switch on the lappy, but not both monitors at the same time. I suspect that it might have something to do with the display driver, because Windows 7 used to work fine and the linux on the other partition works fine as well.
I am including some screenshots. The resolution option is locked to 1024x768. The driver being used is the Microsoft basic display driver, I think the driver should be ATI. I have already tried updating the driver from windows update but got nada.
Hope someone can help.
