Bro, I appreciate your program, but I need your help.
I'm running 2 5970s for scrypt mining on cgminer using xubuntu 13.10
I have amd catalyst 12.8 and AMD APP SDK v2.9

When I run cgminer as
./cgminer --scrypt -o stratum+tcp://mypool:port -u user -p x --shaders 3200 --intensity 13 my screen blacks out
If I use the same command, but replace shaders to 1600 my pc freezes.

So I've trued and find my max thread-concurrency, and it looks like it can't get higher then --thread-concurrency 1024

I've been searching for a week and was able to get my rig to 1500khash/s but wasn't getting any shares.
Could you please try and help me?
