Default Twinview messy / modeline generator problem?

Hello,

I have been working on editing my XF86Config file for a number of hours tonight and I have been able to get both displays to display the proper resolution although I am getting some crazy lines across my display like the frequency is wrong or something. Anyway I have the refrence CD for both of my 15" LCD's and I notice different values than those generated by the online version of the modeline generator (I first tried the values that it gave me when I entered 1024x768 @ 75hz; which my monitor documentation gave me as the max resolution).

Specifically the online modeline generator gives me

# 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz
Modeline "1024x768_75.00" 81.80 1024 1080 1192 1360 768 769 772 802 -HSync +Vsync

which I changed the pclk value to coincide with the one listed in the monitor documentation

anyways neither the generated modeline or the one I edited work so maybe my problem isn't modelines but I tend to think I have modeline problems.

I am attaching two jpg images from my manual and also the XF86Config file I made and I would appriciate it if someone could help me get rid of these crazy flashing lines so I could use my new computer.


Oh I almost forgot the motherboard has onboard dual head GeForce 4 MX. It is an HP d325 microtower and the monitors are 2 15" Compaq 5017m LCD monitors.

Default anybody?

would anyone take a look at my scanlines and the images from my manual posted above and comment if they think my problem is modeline related also?

thanks

# NOTE: This is a NEW IMPROVED version of XF86Config-fbdev that uses the vesa

# This XF86Config file is designed for use with the VESA framebuffer.
# This generic interface should work with nearly all video cards
# (although not every card will support every resolution).

# With the new driver, it should no longer be required to have frame buffer
# support in the kernel, or to run it on the console.
