While I'm waiting on that answer... Go to your /etc/defaulat/grub file
Code:

cd /etc/default/
sudo gedit grub

Find the line
Code:

# GFXMODE=640x480

Edit it to read
Code:

GFXMODE=1024x768x24

Save and exit.
Code:

sudo update-grub
sudo reboot

Try and see what happens... If it does work, go back to that file, add the # character back in to comment out and the a line saying
[code]
GRUB_GFXPAYLOAD=text
[/code[
Save and exit.
Code:

sudo update-grub
sudo reboot

Try and see what happens...
Hi again sorry for delay
No this new grub file doesn't work, one thing I noticed was my laptop was working overtime when I rebooted with the new grub file and I noticed on shut down " the screen was very garbled" but I could see an error "no suitable kernel found"
Please comment on the following, my xxrandr -q file with computer working on new kernel 2.6.28-9, "monitor "disconnected because it crashes both screens"

Okay then change "GRUB_GFX_MODE-640x480" > keep the line "GRUB_GFXPAYLOAD=text" < add "acpi_osi="Linux"" to the GRUB_CMDLINE_LINUX_DEFAULT line... update-grub and try again.
