So I've been a lurker around here for a little while and I have recently tried to move into mining through Ubuntu but I'm having some trouble getting my 2 7970's to be recognized. I followed the guide here
https://bitcointalk.org/index.php?topic=50388.0However when I get to checking my devices it says
"No device specified or device not found, use -d to specify one of the following"
Then it just lists my CPU
Any ideas?
