During installation as soon as the computer starts to boot continually tap any key until you see this screen, parameters then choose nomodeset, the Ubuntu install cd should now boot to the desktop.

After you install Ubuntu follow the directions below to set the resolution permanently on your installed Ubuntu desktop.

If you do not press any keys when the computer is booting up it should load Ubuntu, this is if Ubuntu is already installed, but this may take a couple of minutes, then you can do the following.

If it is only happening in GRUB and you can boot into Ubuntu then please do this:

sudo apt-get install gksu


gksudo gedit /etc/default/grub

and change this line:


to this:


Then save and exit the document.

Then do:

sudo update-grub

If after you install Ubuntu it will not boot to the desktop Hold down (right) SHIFT to display the menu during boot. In certain cases, pressing the ESC key may also display the menu you will get this screen boot menu then press the e key and go down to the line that starts with linux /bootvmlinuz after the words quite splash add nomodeset, then press F10 to boot.

After you boot if you had out of range issue's still follow the directions above for making the changes permanent in an installed Ubuntu desktop.
