[Techtalk] resolution woes

[Amy Hussey]

Maria,

I was having this issue on ubuntu.

Are you, perchance, using openchrome as your driver?  I'm adding the info
about my xorg.conf to maybe help you.

I don't know if it will help or not.

xorg.conf:

Take a look and see if it will work for you.

I wish you luck.
