Hardware specs for my mining rig:
Power Supply 900W
Motherboard MSI 870-G45 AM3 AMD 770 ATX
CPU AMD Sempron 140
Memory 2GB DDR3
2 x Graphics card Radeon 6850
Running ubuntu 11.04 x64, using poclbm miner version "20110709" (also tried phoenix).
There is only 1 monitor connector to the 1 monitor I have. DISPLAY=:0
Ran all of the steps in this article:
http://forum.bitcoin.org/index.php?topic=7514.msg110334#msg110334Ati config shows the 2 devices
aticonfig --lsa
No protocol specified
* 0. 01:00.0 AMD Radeon HD 6800 Series
1. 02:00.0 AMD Radeon HD 6800 Series
* - Default adapter
Running poclbm.py without a device shows the 2 devices:
./poclbm.py -d0 http://me@yahoo.com_0:password0@pit.deepbit.net:8332
No device specified or device not found, use -d to specify one of the following
[0] Barts
[1] Barts
[2] AMD Sempron(tm) 140 Processor
I can run a miner on d0 and d2 without any trouble, and I am getting normal hash rates for the GPU and CPU
ps -ef | grep pocl
me 1749 1748 1 02:27 pts/0 00:05:38 /usr/bin/python ./poclbm.py -d0 http://me@yahoo.com_0:password0@pit.deepbit.net:8332
me 2088 2087 98 03:41 pts/1 05:56:53 /usr/bin/python ./poclbm.py -d2 http://me@yahoo.com:password2@pit.deepbit.net:8332
Every time I run poclbm.py with -d1, the program never shows it as processing hashes. CTRL-C and kill will not stop poclbm. kill -9 on the poclbm process crashes the entire computer.
I tried setting DISPLAY=:0 and =:0.1 before running poclbm.py with no luck.
Do I need a connectore out the back of the other graphics card? How else can I troubleshoot this?
Thanks
EDIT: I am running x-windows, do I need to shut it off to run 2 card mining?
