Changing Resolution and Installing ATI drivers

[Phobos419]

Hi all,
I'm attempting a permanent install on my laptop (an Aspire3820TG) with an ATI 5470. I can boot and get a desktop at 1024x768 but I can't get the resolution up to 1366x768. (Worked fine on Ubuntu 10.10) I attempted to install the ATI (11.1) driver but afterwards I just get errors.
I've tried:
aticonfig --initial=check which is good but then when I try
startx
it just gives a black screen with an underscore at the top left, the last of the terminal output mentions error with "OggS-SEEK" and "diff-requested" and if I exit X with clrt+alt+backspace it mentions a bunch of warnings with "ARTS"
So I ran...
fix-vesa
startx
and I can't get x to start. It just gives errors about no screens found and "(EE) No devices detected" . Attached are some logs from after everything including my modified xorg.conf. Any suggestions?

Exactly the same problem here.
Tryed everything. Even ton of scripts and solutions from internet, but none of them helped to set resolution to 1366x768
