CentOS - Nov 2005 - x windows dell inspiron 1200 setting for 1366x768

I am attempting to setup a dell inspirons 1200 laptop
media accelerator 900 from intel is the chipset so I am using the i810 
driver.
In the default 1024x768 everything is fine.

I am trying to setup the external port not the LCD to be 1366x768.
I added a modeline to xorg.conf of:
Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "LCD Panel 1600x1200"
        HorizSync    31.5 - 90.0
        VertRefresh  60.0 - 60.0
        ModeLine     "1024x768" 65.0 1024 1048 1184 1344 768 771 777
806
-hsync -vsync
        ModeLine     "1024x768" 54.2 1024 1048 1184 1344 768 771 777
806
-hsync -vsync
        ModeLine     "1366x768" 85.5 1366 1494 1624 1798 768 770 776
795
-hsync +vsync
        Option      "dpms"
EndSection

There is a line in the log file of:
(II) I810(0): Monitor0: Using hsync range of 31.00-70.00 kHz
(II) I810(0): Monitor0: Using vrefresh range of 50.00-85.00 Hz

virtual size)
(II) I810(0): Not using built-in mode "1280x1024" (width too large for
virtual size)
(1366x768,Monitor0) mode clock 100000MHz exceeds DDC maximum 110MHz
(1600x1200,Monitor0) mode clock 162MHz exceeds DDC maximum 110MHz
(II) I810(0): 6632 kBytes additional video memory is required to

I looked at the specs of the media 900 and it does something like 25XXx10XX

What am I not setting up correctly to see the 1366x768?

THanks so much,

Jerry

I had a similar problem trying to set 1400x1050 on a Siemens Fujitsu
Laptop. The fix for me, was to use 915 resolution from
http://www.geocities.com/stomljen/ as it seems the Intel video bios has
a limited set of resolution modes

Hope this helps

Dean,

THanks I have 1 question. on centso 4.2 X starts real early...
Where do you run the 915resolution command? I put it in 
rc.local and it did not seem to work.

THanks,

Jerry

That's where I put it and it worked fine.

I tested first by booting to run level 3 running "915resolution 4b 1400
1050" and then started X. This worked so I just added the same command
to rc.local. The desktop now boots by default to 1400x1050 in run level
5.

My tests were on Siemens Fujitsu Laptop E8020D with Centos 3.6 and I had
to replace XFree86 with the latest development version before using
915resolution as I could not get X to display anything other than a
black screen, even with the vesa driver.

Dean.
