I'm trying with (below my sh file):
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
cd /home/x/cgminer-3.7.2-kalroth/
find *.bin -delete
sleep 3
cgminer --scrypt -o stratum+tcp://stratum.fast-pool.com:3333 -u user.x -p pass --thread-concurrency 24550 --lookup-gap 2 --auto-gpu --gpu-engine 950 --gpu-memclock 1250 -w 512 -I 20 --gpu-powertune 20 --auto-fan --gpu-fan 40-100 --temp-overheat 90 --temp-target 85 --temp-cutoff 95 -g 1
This gives me average ~660 kh :(
I was trying also with config from GUI miner for windows called "R9 290 high":
cgminer --scrypt -o stratum+tcp://stratum.fast-pool.com:3333 -u user.x -p pass --thread-concurrency 32765 --lookup-gap 2 --auto-gpu --gpu-engine 950 --gpu-memclock 1250 -w 256 -I 20 --gpu-powertune 20 --auto-fan --gpu-fan 40-100 --temp-overheat 80 --temp-target 75 --temp-cutoff 85 -g 1
but it gives e something like this:

Above configs works fine (better hashrate) on windows 7 64, but i prefer to use ubuntu beacause windows is unstable.
Anyone can help me?
I have installed latest catalyst, sdk ofcourse.
