cgminer 3.7.2 does not detect GPUs

[Valansch]

Hello!
I followed this guide to setup my xubuntu 12.10: http://www.reddit.com/r/litecoinmining/comments/1fb5qs/step_by_step_headless_linux_setup_from_scratch/

Although aticonfig --list-adapters gives me the correct output:

No protocol specified
* 0. 01:00.0 AMD Radeon R9 200 Series
  1. 04:00.0 AMD Radeon R9 290 Series

* - Default adapter

i do not know why my cgminer does not detect the GPUs.

When i type ./cgminer -n i get

Can someone help me?

If memory serves me right, error -1 is driver error. Try installing 13.12: http://support.amd.com/en-us/download/desktop?os=Linux%20x86_64 (if you're using 64bit)

Okay thanks.  Next question: how do i remove my old driver? Can i just overwrite it?


Edit: I tried the 14.1 Beta driver, still the same problem :/

Did you try 13.12 or did you jump right into the beta drivers?

Also, post your settings here.
