Title: CGMiner Problem on Xubuntu 12.04. **Reward for problemsolver** Post by: Xubu on February 08, 2014, 08:29:33 AM 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.

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.
