I'm new to linux and have just loaded mandrake 9 on a brand new Dell. it has intel 845 graphics and a dell E151FP flat screen monitor. there are several problems when running the gnome desktop:

1. The monitor is saying that the signal is out of range. I presumed this was the frequencies so have tried adjusting the XF86Config-4 fil accordingly, but it still does not work.

2. The screen does not display well. text and pictures are sometimes blurred. I think this is due to the refresh rate not being right.

3. I cannot change the resolution to anything higher than 256. The error message appears at start of xwindows saying that it cannot find a screen.

Here is the config file:
