that's what I got when I ran cvt.. good!

Then create your script:

#!/bin/bash

/bin/xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
/bin/xrandr --addmode VGA1 1920x1080_60.00
/bin/xrandr --output VGA1 --mode 1600x900_60.00



Not sure if this will work since your external monitor may not be connected at boot time, but worth a shot
I created the script, will give it a try next time I boot... having a live CD handy just in case:) I should at least be able to either boot to safe mode or command line... if it needs fixing. and normally I see the DELL logo come up on the laptop, then both the laptop & external monitor have the login window, in 1024X680 mode..
