./cgminer -k diablo -v 1 -w 256 -I 7 (Diablo Kernel, worksize 256, Vectors 1, Intensity 7)

This might sound stupid, but try adding a variable for all 4 of your GPUs. For example:

./cgminer -k diablo,diablo,diablo,diablo -v 1,1,1,1 -w 256,256,256,256 -I 7,7,7,7 --gpu-mediff -150

I've tried this and it doesn't work either. Thanks for the suggestion though, it was worth trying.

I played around with Xubuntu some more last night (again, everything runs fine on Windows, but I prefer Linux), and still no luck. I'm surprised there are more than just a few having this issue, and no one's resolved it yet. The only thing left to try is a different, non-Ubuntu (or Debian-based) Linux distro, as that would help us tell if it's either just some bad packages or if it's the Linux drivers themselves.

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

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

I had the same problem yesterday trying to setup 2x 7950's - exact same issue as Vuxil. One was mining half the hash rate, the other was running locked at 300 / 150 on Xubuntu 12.04.

I gave up and switched to Windows, and now I'm doing 530 KH/s per card with CGminer - and can push almost 600 KH/s, but it puts out too much heat for my fans to keep up with. I wish I could get it working on Xubuntu, but it's just not happening. Sigh.

If you guys have any luck, I'll be watching this thread.

Got any hints as to what you had tried, so we're not double working what you've already done?

What version of Catalyst were you running?
Kernel version?
Tried locking the kernel on install so it doesn't upgrade?

Also, have you tried an external fan? I got one for $15 at walmart and mine went from overheat till it shut down (100C) idle to 70C at full load.

You guys have done more than I did with it. I got frustrated much faster, and swapped to Windows. I didn't do any custom installs of specific drivers, just the latest. So I'm afraid I have nothing new to add Sad

I was going to pickup a small fan. I think I need to do that now so I can run it harder. How big of a fan did you get? Small 12"? Or a big box fan blowing over the cards?

I feel that ubuntu 12.04 is much better and has a better speed. 12.10 is still being tested & developed further.

I would stick with ubuntu 12.04 for the time being, then look in the comments of that guide you followed. In the comments section there are people asking similar questions to you. Because I don't know your setup I can't really give you a perfect answer, if I just copied what they said in the comments it could be wrong. So you might want to check the different solutions they give, at least then you may have some idea how to correct it.

If you're referring to the rdmsnippets.com article I linked, that's me in the comments (the other 2 than marc). I have a few other comments awaiting moderation.

Are you using multiple GPUs on Ubuntu 12.04? if so, what version of Catalyst are you running?

I'm worried that Catalyst 12.8 doesn't support kernel 3.5 which 12.04 will update to (if I'm reading this correctly). I'll try following the instructions here (http://askubuntu.com/questions/178324/how-to-skip-kernel-update) to hold the kernel to the ship version, which i believe is 3.2

I probably just missed this. I saw your comment in the referenced thread, but I didn't see if you had tried,

Code:

sudo aticonfig –initial
sudo aticonfig –adapter=ALL –initial
sudo reboot

Yeah, I'm way past that.

All cards show up in aticonfig --odgc as well as fglrxinfo. I've also done them with -f with no avail. I'll try it again but I'm pretty sure it's not the problem.

I have not yet tried...

sudo amdconfig --input=/etc/X11/xorg.conf --tls=1

however I'm pretty sure that getting a good result from flgrxinfo & aticonfig --odgc would mean the xorg.conf is loaded properly. Please let me know if that's incorrect.

No luck with BFG either. I'm convinced it's something about the Linux drivers now, but others report success so idk.

With Catalyst 13.1, multi GPU, and Ubuntu 12.x?

Got any links?

So on Windows I had bad luck with the latest catalyst drivers (13.1) - reverting a year earlier to Catalyst 12.3 seems to work much better. Looks like the most recent firmwares try to do too much and cause some interference with mining, at least from my observations.

Also, the SDK and AMD_APP should come packages in Catalyst 12.3, so I think you are already including them in your install.

I'm at a bit of a loss here right. The only thing I have left to try is something other than cgminer I think. My other suspicion is the Linux AMD driver is doing something in the background that we don't know about yet. Other people have had good luck though, so Huh

If it works in Windows, I'm pretty sure you don't need a dummy plug.

I really have no idea how to uninstall AMD_app, or anything for that matter. I've reinstalled 12.04 around a half dozen times, usually from a botched ati driver install and not knowing how to get X to reload. I used a bfg install tutorial (http://debianhelp.wordpress.com/2012/01/02/bitcoin-mining-in-ubuntu-with-bfgminer/ i think) and didn't do the AMD_app or SDK.

I just got home and only have a few hours to screw around but I have 11.04 installed on another stick and I'll see how far I get, probably get it finished in the morning.

Did you try a dummy plug?

If you don't mind trying an experiment, load up bfg miner and see what that does then uninstall ADM_APP and try it again. Last night I followed install guides for BFG and I got it running (cgminer won't run w/o firegl/opengl) but once I installed AMD_APP cgminer ran but BFG slowed WAY down. Something tells me that it's causing problems.

If not that, ckolivas suggests using a older driver (12.x from what I gather) (https://bitcointalksearch.org/topic/m.1719697) but the 12 series doesn't support the Xorg version from 12.08/12.10. I'll likely look at trying to get my machine running on 11.04 tomorrow morning and I'll let you know how I make out.

I can confirm both of my cards work under Windows very superbly using CGMiner + the same parameters I would use in Linux, so it's got to be something related to the Linux drivers or mining software.

I still have my Linux partition. Never tried BFG, only CGMiner, but I can give it a try soon. Where did you remove ADM_APP from? Is it just in /etc/? And, I haven't been using dummy plugs

What distro are you using?

I am trying (http://www.techpowerup.com/forums/showthread.php?t=86507), or will as soon as Xubuntu finishes loading on this flash drive (sure is taking it's merry time). In short, some people it helps to jump 3 pairs of pins with a resistor on a dvi->vga converter to make the card think that there is a monitor plugged in.

Where I got the tip from (http://rdmsnippets.com/2013/03/20/bitcoin-mining-with-ubuntu-12-04-tls-and-cgminer/) says that cgminer told him that his card was disabled, where I'm showing them all running at slow speeds.

Is your CGminer showing Device 0 and 1 running, or just 0?

I've tried Xubuntu 12.04 as well as 12.10. I have two devices running, with two GPUs detected and identified; CGMiner displays information on both. My issue is just I can't get my second card to accept CGMiner parameters.

I've tested both cards individually and they both work. It's just not working right when I try to use both simultaneously. I'm thinking it's either Linux, my motherboard, or my powersupply (in that order of likeliness). I am going to do some testing with Windows today and will let you know how it goes

It wasn't a dummy plug (from what I can tell). Grr.

I am having the same problem but with 2 HD 7850s. I've rolled back as far as 12.3 and still no dice. One GPU is at 99% and the other is sitting at 0%
