Custom modeline


I was able to generate a modeline for my 1440x900 flat panel laptop display. How do I insert it into my XF86Config-4 file so that my laptop can finally have a good resolution? As a second note, why is it that once my new nvidia drivers were installed, the resolution won't go above 1024x768? Before when I used the vesa drivers, I could at least get 1280x1024. Any help would be great. I don't want to go back to windows in order to get a good resolution.

Here's my XF86Config-4 file as you can see the modeline for the 1440x900 resolution is already in there but it doesn't work:

Well, I don't mean to ramble but it seems the hsync is out of range for anything higher than 1024x768. Windows can display 1440x900 and the hsync for that rez at 60Hz is about 56.7kHz. The EDID-specified sync for my display is 55kHz. I tried to tell Xwindows to use a hsync range of 31.5-60kHz but it seems that because of EDID it ignores my setting and falls back to a sync range of 55Khz max which won't display 1440x900. Please help, is there a way to turn EDID off so that Xwindows uses my settings instead?
