ATI 290x on Ubuntu 14.04

[alegro]

I've been trying to get Ubuntu 14.04 to see the Radeo 290x cards for a while with no success.

This is the message I'm getting

aticonfig: No supported adapters detected

I tried first installing ATI Catalyst (http://support.amd.com/en-us/kb-articles...river.aspx)

I then tried this guideline
http://wiki.cchtml.com/index.php/Ubuntu_...tion_Guide

But with no success.

Did anyone run into this problem? What do you guys recommend?
