To get everything working in Ubuntu 13.04 , it looks like you need the 3.10 linux kernel for the wireless network, which requires the 13.8 beta catalyst driver from AMD. Then you have to modify /etc/rc.local to fix a permissions issue with /proc/ati.
What I did was:
Install the 3.10.7 kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10.7-saucy/
using the 64 bit directions from
http://linuxg.net/how-to-install-kernel-3-10-7-on-ubuntu-linux-mint-debian-and-derivates/
Then install the following package
Sudo apt-get install dkms
Make the packages for the 13.8 drive, similar to section 3 of
https://help.ubuntu.com/community/BinaryDriverHowto/ATI
Modify /etc/rc.local
sudo cp /etc/rc.local /etc/rc.local.original
sudo pico /etc/rc.local
and insert the line "chmod -R 777 /proc/ati" before the "exit 0" line
Hit ctrl-o to save
Hit ctrl-x to exit
I think that was everything
startx
