How do I install drivers for an AMD Radeon HD 6450?

I'm running Ubuntu 11.10 x86 with PAE on GNOME3. I have a Radeon HD 5750, Phenom II 955, and 6GB of cheap DDR3. I want to install the newest version of the proprietary AMD driver for the GPU, however AMD's site is giving me some nonsense about a duplicate header and won't download the file. When using Ubuntu's built-in installer, there are two options: one with post-release updates and one without. The one without installs fine, but renders gnome-shell unreadable (applications work fine, interestingly). The version with updates, however, cuts off quickly and tells me to view /var/log/jockey.log. I have tried it more than a few times, and have rebooted multiple times. Is there a way to clear any caches? The program itself crashed the first time through, and I suspect that there might be some screwy files acting up.

Here is jockey.log, in case that helps.

Thanks in advance.

I would install the driver manually.

1) Download from AMD: http://www2.ati.com/drivers/linux/amd-driver-installer-12-1-x86.x86_64.run

2) sudo apt-get --purge remove fglrx*

3) sudo sh amd-driver-installer-12-1-x86.x86_64.run --buildpkg Ubuntu/oneiric

4) sudo dpkg -i *.deb

5) sudo aticonfig --initial -f

6) reboot
