First of all: I am familiar with mining. I am running a 3 X 7950 rig alredy on Xubuntu 12.10. Without any problems. I bought some new hardware for a new rig.

I have a strange problem when i start cgminer on my new rig. I installed Xubuntu 12.04, cgminer 3.7.2 and the AMD catalyst 13.12 driver.
I can start mining, but for some reason i can't accept any shares, and cgminer is showing some strange hashrate in GH instead of MH?? See the following link for more information : http://imgur.com/Ht9duZH

I Tried different pools and different versions of cgminer.  They all give the same result.

I think there is a problem with my drivers. I cant figure out.

My setup:

2 X R9 - 280X sapphire toxic.
cgminer 3.7.2
AMD Catalyst™ 13.12 Proprietary Linux x86 Display Driver

Here is what i did so far.

Update and Upgrade

sudo apt-get update
sudo apt-get upgrade

Install dependencies
sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4
sudo apt-get install lib32gcc1
sudo ln -s /lib/x86_64-linux-gnu/libudev.so.0 /lib/x86_64-linux-gnu/libudev.so.1

Install Catalyst driver

mkdir catalyst13.12 && cd catalyst13.12
wget --referer='http://support.amd.com/en-us/download/desktop?os=Linux+x86' http://www2.ati.com/drivers/linux/amd-catalyst-13.12-linux-x86.x86_64.zip
unzip amd-catalyst-13.12-linux-x86.x86_64.zip
chmod +x amd-catalyst-13.12-linux-x86.x86_64.run

sudo ./amd-catalyst-13.12-linux-x86.x86_64.run --buildpkg
sudo dpkg -i fglrx*.deb

sudo aticonfig --lsa
sudo aticonfig --adapter=all --initial
sudo reboot

I startup cgminer with a shell:


#!/bin/sh
export DISPLAY=:0
export GPU_MAX_ALLOC_PERCENT=100
export GPU_USE_SYNC_OBJECTS=1
cd /home/user/cgminer-3.7.2-x86_64-built
/cgminer -g2

My config file that gminer uses :

"pools" : [
        {
                "url" : "stratum+tcp://mine1.coinmine.pl:6300",
                "user" : "xxx",
                "pass" : "x"
        }
]
,
"intensity" : "13,13",
"vectors" : "1,1",
"worksize" : "256,256",
"lookup-gap" : "2,2",
"thread-concurrency" : "8192,8192",
"shaders" : "0,0",
"gpu-engine" : "1080,1080",
"gpu-fan" : "30-75",
"gpu-memclock" : "1500,1500",
"gpu-memdiff" : "0,0",
"gpu-powertune" : "20,20",
"gpu-vddc" : "0.000,0.000",
"temp-cutoff" : "95,95",
"temp-overheat" : "85,85",
"temp-target" : "75,75",
"api-mcast-port" : "4028",
"api-port" : "4028",
"expiry" : "1",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",

Am i missing something in my setup?

Any help would really be appreciated. Teamviewer available here on my Windows Laptop with putty for the ssh login to the rig. I give a reward of 0.025 BTC for the person who can solve this problem via teamviewer.

You need to use "scrypt" : true, in your cgminer.conf
