Hi Rob - Happy ThanksGiving:
First - there are specific and well known bugs in Ubuntu with that Intel Integrated GMA:
Reference:
http://www.thinkwiki.org/wiki/Intel_Graphics_Media_Accelerator_X3100
Suggestions:
A) Try the 915resolution tool:
1. To install the package run the command ” sudo apt-get install 915resolution “
2. Now run ” sudo 915resolution -l “
3. You should see a list of different modes of resolution, like this,
Intel 915GM VBIOS Hack : version 0.1
Chipset: 915GM
Mode 30 : 640×480, 8 bits/pixel
Mode 32 : 800×600, 8 bits/pixel
Mode 34 : 1024×768, 8 bits/pixel
Mode 38 : 1280×1000, 8 bits/pixel
Mode 3a : 1600×1200, 8 bits/pixel
Mode 3c : 1920×1440, 8 bits/pixel
Mode 41 : 640×480, 16 bits/pixel
Mode 43 : 800×600, 16 bits/pixel
Mode 45 : 1024×768, 16 bits/pixel
Mode 49 : 1280×800, 16 bits/pixel
Mode 4b : 1600×1200, 16 bits/pixel
Mode 4d : 1920×1440, 16 bits/pixel
Mode 50 : 640×480, 32 bits/pixel
Mode 52 : 800×600, 32 bits/pixel
Mode 54 : 1024×768, 32 bits/pixel
Mode 58 : 1280×800, 32 bits/pixel
Mode 5a : 1600×1200, 32 bits/pixel
Mode 5c : 1920×1440, 32 bits/pixel
Mode 60 : 1280×770, 8 bits/pixel
Mode 61 : 1280×770, 16 bits/pixel
Mode 62 : 1280×770, 32 bits/pixel
Mode 63 : 512×771, 8 bits/pixel
Mode 64 : 512×771, 16 bits/pixel
Mode 65 : 512×771, 32 bits/pixel
3. To change to the desired mode, say for example, mode 5a, which is 1600×1200 with 32 bpp, you would run
” 915resolution 5a 1600 1200 32 “
Now to fully set the mode, type sudo gedit /etc/default/915resolution,
a relatively short text file will pop up, edit this file by changing
MODE to the MODE that you selected. Eg, the mode line should now be ;
MODE=5a
Change the XRESO and YRESO values to correspond with your selection, for our example, they should look like this;
XRESO=1600
YRESO=1280
Finally, set the BIT value to the bpp you selected, in our case,32;
BIT=32
Now save the file and exit it.
4. Now restart x by pressing
<CTRL>-<ALT>-<BACKSPACE>. The 1st time you log in, X might
crash and restart itself at the new
resolution, so don’t worry if it does that.

A) It appears as if your modeline is not correct - Go here and get the correct modeline:

C) Here's an example configuration from someone who had finally successfully done both with an Intel x3310 and external monitor:
