gcminer with ATIRADEON HD3600 on ubuntu 12.04 64bit headless won't detect GPU I am following this guide: http://rdmsnippets.com/2013/03/20/bitcoin-mining-with-ubuntu-12-04-tls-and-cgminer/

But it won't work on my server (Specification's are in the Subject-field)

I get this error:

koen@gorgabal-Server:~/bitcoinmining$ ./cgminer/cgminer -n

I can't switch to windows because of several reasons, does anybody have an idea of what I am doing wrong? 

Thanks in advance!
ps: I have used linux for several years now, so I know my way around. This is a fresh server installation.
OpenCL is not supported on 3xxx series cards.  Although it's not completely impossible to mine on a card that old it will be very difficult.  Also, a card that old will produce less than 1 MH/s which will only be fractions of bitcoins.  I wouldn't waste my time fighting the Radeon 3600.

If you are serious about mining check out the 5xxx and 7xxx series cards.  Or better yet, look into ASICs.
