Dell Inspiron 5150 XF86Config File Redhat Linux 9

We had a wee problem getting the screen to work nicely with X. 1400x1200 was the res that we wanted. Seems that if you increase the V and H scan numbers a fair bit it all works - checkout the "monitor" section.
The touchpad also seems to be quite happy with these settings.
Yes, you do need to get the graphics card driver from Nvidia.
