I am building my 4x 280x rig today and was planning on following Cryptobadger's guide, so thank you!
You can't use cryptobadger's guide for 280's, he uses apt-get for fglrx drivers but they don't work with the 280x.
You need to go get the drivers from AMD's website, build the install for your version (I suggest saucy salamander) and install it. You need to uninstall the fglrx you installed with apt-get though, I don't know how. I reinstalled
I am also a real newbie to linux, but I managed to mangle enough of cryptobadgers guide as well as google-fu to find out how to build and install amd catalyst on Linux. Should be some good search terms for you in this post. Hope you get it working!

Also curious if you resolved this? Let us know.
try running
Code:
sudo aticonfig --adapter=all --initial --force
and make sure to install the SDK before the drivers. do all of this from init 3. this procedure has worked the best for me. also shouldn't thread concurrency be 8192 instead?
Were you able to find a solution to your problem?
I'm also planning to buy the same cards, and am interested in the answer, in case I face the same issue.

Hello guys, i got my mining hardware this week and started setting it up, following the guide of Cryptobadger: http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-linux/
The only difference is, that im using a r9 280x Sapphire Dual GPU. Currently running solo. Because i want to test first before i add additional GPUs. Before switching to Xubuntu i used the GPU on my Windows 7 PC. It was running nicely with 780kh/s but on Linux only 600kh/s. =\
Following the guide everything works nicely. Beside one error.
got me ...
... everything else works properly. Seems like the cgminer settings are not the problem for that, more likely something with the drivers or maybe 280x opimized kernels for cgminer.
cgminer settings are this:
Im trying to fix this problem the whole week but nothing really helps just getting 620kh/s at maximum.
Im kind of a Linux noob, so be warned.
Cheers!
