Having issues getting my mining rig working - need help

Hello all,
This is my first time posting to the forums, so hopefully I am posting this to the right place.

As is stated in the title, i cant quite seem to get my rig properly set up to mine. I've been following this guide: https://ethereum.gitbooks.io/frontier-guide/content/gpu.html
I think the issue has something to do with amd drivers or opencl or something. I have an R9 290 on ubuntu 14.04.

ethminer and eth both give me very similar errors when I try to mine with my gpu:

blue@blue:~$ ethminer -G -M
Invalid MIT-MAGIC-COOKIE-1 keymodprobe: ERROR: ../libkmod/libkmod-module.c:809 kmod_module_insert_module() could not find module by name='fglrx'
modprobe: ERROR: could not insert 'fglrx': Function not implemented
Error: Fail to load fglrx kernel module!
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly
Segmentation fault (core dumped)
and

Invalid MIT-MAGIC-COOKIE-1 keyNo GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument

Additionally, I'm not sure whether this matters, but when I listed adapters it showed:
blue@blue:~$ sudo aticonfig --lsa
* 0. 01:00.0 Supported device 67B1

* - Default adapter
which differs from what is shown on the guide:
sudo aticonfig --list-adapters
* 0. 01:00.0 AMD Radeon R9 200 Series

* - Default adapter

Thank you in advance for your time! If anyone could point out where I may have went wrong, it would be greatly appreciated!
