Another D2500 Video Resolution Problem with Lucid

Another D2500 Video Resolution Problem with Lucid was created by KenC
Was using Ubuntu LinuxCNC 2.6.7 (upgraded from Linuxcnc 2.5 Live CD) on Lucid until recently when I have to re-install everything from scratch
Fear over my no-brand SAW touch screen wouldn't install properly, I decided to stick to Ubuntu 10.04LTS
Hardware are:
Intel Atom D2500hn Mobo, 1GB RAM, 8GB SSD, no-brand 19" 5:4 SAW touchscreen monitor. Huawei E303 A.K.A HiLink 3G USD dongle.
So I happily Downloaded a copy of Ubuntu 10.04.04 LTS Live CD, burnt it on a USB stick with rufus2.1.
Then I get a nice 800x600 default screen.... will get back to it after some other chores...
The Dongle went on easier than I could remember. only 2 lines on the terminal...
Touch Screen was automatically detected (which took me over 2 weeks to fix). and response to Elotouch very well. with my new found knowledge in /***/***/X11/xorg.conf.d instead of generating/rename/move/editing a xorg.conf file, the calibration and making it permanent was done swiftly.
Now the 800 x 600 display, fiddled with the /xorg.conf.d/*.conf files managed to pop it to 1280x1024 max. ( not nice consider it strains my degrading eye reading at this resolution). 1024x768 came along just fine and 1400x1200 also came uninvited.
BUT, what I really need is 1024x819 which is just about right for easy touch screen operation. I use cvt and xrandr to generate the modelines and plug them into my /xorg.conf.d/10-minitor.conf and the pc said, it doesn't support this resolution..... yes, you can do 1400x1200 but not 1024x819 nor 1000x800....
Worked on it for almost a week since ... Seriously need help!!!
My latest code gives 1400x1200, 1280x1024, 1024x768, 800x600 but not 1024x816 and 1000x800
/usr/lib/X11/xorg.conf.d/10-minitor.conf

Hi
You have 1024x768, that is as close as you are going to get.
The resolutions are standards and based upon pixel density with a given screen size.
You will not be able to select an arbitary value, which is not a factor of that equation

I was digging myself into a dead end... again.... 
Anyway, I deleted the "imaginary" modelines and modes from the ,conf and live with it.
Thanks for the heads up Arceye.
