Same issue for me with Gigabyte 4x4950 on Ubuntu 32. Only one gpu is in use while cgminer happily says that all cards are mining. nothing helps.
I don't have dummy plug but looks like it is the only option to fix the issue. So Ubuntu DOES NEED dummy plugs.
You can hatch together one with some resistors. Didn't seem to help me at all. |

Crud, I just ran into this on gentoo after updating my system. Fortunately aticonfig --adapter=all -f --initial brought it back to life.
EDIT: I put a dummy dvi plug on the 2nd card while running these commands and booting the first time.
can you pull the dummy plug, restart cgminer and see if both cards work? it would be nice to know if it's only on set that it needs the dummy plug, or always. |

Looks like I'm switching to windows. I've tried a few more times on 12.04 and 11.04 x64 with no luck.

2. 1GH/s, pool mining? How long would it take you average to get 50BTC at current difficulty?
Over 24-26 months, not adjusting for increases in difficulty of course. Also, google these terms. bitcoin calculator bitcoin hardware mining comparison |

Sounds like we have a volunteer to write up that FAQ then.

I don't think you got what I was laying down.
If you were to either put in a bunch of money to buy BTC or a rig, dollar for dollar, in somewhere between 3-5 months from now the miner will have more bitcoins. When mining gets unprofitable (or undesirable), the miner also has some equipment to sell off.
It doesn't matter what price point BTC goes to. In fact, the higher the price, the better off the miner is.
we'd need a hash rate of 300Th/s to make $150/BTC not profitable for video cards (5x hash power of now). As the price goes up, so does the mining margin.

I constantly get questions about mining from people who have just heard about bitcoin. Is there a good post somewhere I can point them to? I think it should include the following points:
1) If they think the price is going to go up a lot, it is much better to buy coins than hardware
2) Info about what ASICs are currently doing to mining, how long it will take to get an ASIC, the risks of ordering an ASIC now, refund policies, and what the mining environment will be like once their ASIC finally arrives.
3) Electricity costs for running GPUs and CPUs and ASICs
4) General discouragement. They are two years late to the party. Newbies should be buying coins, encouraging merchant acceptance, and building the economy, not wasting time learning how to mine or giving money to semi-scam companies.
Have you ever considered that you may just be wrong? 1. At current hash rate a $2000 rig will make just over 4btc/month. At today's cost, that same amount would buy around 14 BTC. if everyday were like today, mining would have a BEP of <3 months. Even with network expansion, actual BEP will be <6 months. 14BTC will only ever be 14BTC, where the rig will keep chipping away. 2. (what the mining environment will be like once their ASIC finally arrives.) Sounds like the same game to me, just different hardware. 3. If anyone is smart enough to be able to put together a rig and not just run what they brung, I'm sure they're well aware. 4. Let adults make their own decisions, thank you. It may sound noble to keep people from doing what you feel like is a waste of their time, electricity and money, but you just come off as an a-hole. Oh, and just because I'm late to the party doesn't mean I'm not the life of it. |

I played around with Xubuntu some more last night (again, everything runs fine on Windows, but I prefer Linux), and still no luck.
What happened with it? What version of driver did you install? I just did a kernel lock ( http://askubuntu.com/questions/178324/how-to-skip-kernel-update) to 3.2.0.37.45 (had to use pico instead of gedit, as it looks like gedit doesn't load with a standard install). When looking at the "additional drivers" app (little card looking thing by the clock) the beta drivers are listed as 12.11 which makes me think that the proprietary drivers are 12.10. Going to try the built in installer, then the hard way if that doesn't work. |

./cgminer -k diablo,diablo,diablo,diablo -v 1,1,1,1 -w 256,256,256,256 -I 7,7,7,7 --gpu-mediff -150
Did everything but --gpu-mediff -150. cgminer said it was an invalid flag. cat /proc/ati/?/interrupt_info
gives me Device: PCI:5:0:0
Kernel: 0
AsyncIO: 0
Device: PCI:6:0:0
Kernel: 0
AsyncIO: 0
Device: PCI:3:0:0
Kernel: 597359

What happens if you switch around the pci ids in xorg.conf, say to make 6:0:0 correspond to Device[0]-0? You can get the order linux believes the cards are in using,
Cgminer runs about the same. 530Mh/s, says it dropping threads from all GPUs but 'aticonfig --adapter=all -odgc' now says adapter 2 is running full bore. I left dynamic intensity on (just launched ./cgminer with no flags) and GPU 0 would run up intensity. Also, only changing GPU 0's intensity effected my hash rate. On a side note, I had to plug my HDMI into the 4th card to get video, with the other 3 displaying only a white screen. |

You OC it? Try hooking the molex up to a different connector.
Is it on an otherwise stable system?

I tried Xubuntu, but the installer wouldn't format my USB. Probably going to try and do the kernel lock tomorrow morning.
And it formatted this morning, weird. Trying Xubuntu w/ kernel lock. |

Change intensity down to 11.
Downgrade from catalyst 13.1 to 12.8.

I think Open SUSE would be a good next try, it's very GUI driven, so the installation process would be similar to Ubuntu. Note that apt-get will not work in SUSE, but it has it's own package management and repository system.
I'm giving up on Xubuntu, it seems to not be the answer.
Gentoo is more for relatively experienced users, and same with Arch. By advanced, I mean there's more manual work in the terminal.
Manual doesn't scare me, but it looks like installing is a bitch. I tried Xubuntu, but the installer wouldn't format my USB. Probably going to try and do the kernel lock tomorrow morning. What happens if you switch around the pci ids in xorg.conf, say to make 6:0:0 correspond to Device[0]-0? You can get the order linux believes the cards are in using,
I'll try it in the morning, I'm exhausted. |

I have two 6770's (one XFX, the other Sapphire) and each should get around 200MH. I'm only getting 187MH total. This is on cgminer 2.11.4 on Xubuntu 12.04 64-bit.

What am I missing? with your miner running, in another terminal window, type... aticonfig --adapter=all --odgc this will show the load on both your cards. Only one is probably working. |

11.04 was a wash. I installed Catalyst 12.8, although I only had instructions for 13.1 (seemed to be fairly straight forward, unzip, sh ./*.run, dpkg -i *.deb). On reboot it launched to X but the screen was flickering on and off with colored bars.
I'm going to dig up a gentoo iso and load it up.

Sorry if this also fits into the category of "things checked long ago," but could you post your xorg.conf?

EndSection I have 3 gentoo boxes running 2x7950, 2x5830, and 1x5770/1x7950 with minimal problems in the setup if you're looking for a different distro.
Got a step-by-step guide we can follow? |

Turn down your intensity to 6 or 7, maybe lower if needed.

Just a 12" I think. Less than knee height off the floor, just make sure it blows good.
