cgminer @ ubuntu - problem

[rafi365]

Hi!
I've got a problem with cgminer on ubuntu 13.04.
I've installed drivers in that way: http://wiki.cchtml.com/index.php/Ubuntu_Precise_Installation_Guide#Installing_Catalyst_Manually_.28from_AMD.2FATI.27s_site.29
And i've configurate cgminer in that way: https://docs.google.com/document/d/1Gw7YPYgMgNNU42skibULbJJUx_suP_CpjSEdSi8_z9U/preview?sle=true&pli=1#heading=h.8iw8sn49z96c
My HD5970 is installed properly - cgminer see two cores, but while starting cg.sh cgminer freezes at this point:

It can be stucked at this point several minutes and it doesn't start mining - just my fans start spining faster and faster....
Any ideas?
Thanks in advance for yout time and help
Cheers
Rafal
