Ubuntu and screen size(xorg)?

I am only offered a maximum of 1280x768 in my current setup- It is able to display in 1280x1024(in windows anyway). I have looked around and found most of the problems deal with not having options for screen resolution(min res only offer) and use xorg to correct the problem. I'm just not sure if this is the same problem or can I screw up the settings I have now? confused

Monitor EV700 gateway
Onboard 845gl display adapter

 

/etc/X11/xorg.conf.

Follow the current layout under "Screens" for adding a new resolution.

Or, if using Nvidia drivers, the nivida-settings control panel can do the same.

 

I played around awhile and thought I was due for a flavor change anyway....went to suse 10.2 and it gave me the video resolution I was looking for(go figure)

anyway thanks for the help
