I'm having trouble with my Lancelots just turning off after a few minutes or a couple hours

Thanks for the info. I have finally resolved this

I found a file .Xauthority that was owned by root in the home folder. This was causing issues.
sudo rm .Xauthority
reboot -h now
ssh back on the box
DISPLAY=localhost:10.0 ; export DISPLAY
Run up cgminer and everything is working fine :-)

No protocol specified <-- X11 error, didnt you start it?

Hi all,

I have been working trying to configure a guys rig with cgminer on Linux. I have configured everything as normal as I have cgminer working fine on 5 of my own machines with HD 7950 cards. I have also configured cgminer to work with 7970 cards with no problems.

However I keep having issues with this guys setup. Im installing on Ubuntu 12.04 LTS. The guy has several HD5870 cards and one HD5970 card

aticonfig detects all the cards fine e.g
* 0. 01:00.0 ATI Radeon HD 5800 Series
  1. 0a:00.0 ATI Radeon HD 5800 Series
  2. 09:00.0 ATI Radeon HD 5800 Series
  3. 06:00.0 ATI Radeon HD 5800 Series
  4. 05:00.0 ATI Radeon HD 5800 Series
  5. 04:00.0 ATI Radeon HD 5900 Series

The problem is no matter what Catalyst Driver I install I cannot get cgminer to start without throwing out errors.

Currently I get the error.
root@rig:/home/rig/cgminer-3.0.0-x86_64-built# ./cgminer -n

I have now had him remove the 5900 card as I thought it may be down to the number of cards he has hanging off this motherboard. I can see in lspci he has lots of Intel stuff so presume its an Intel based motherboard.

Has anyone any experience of this error?. I have tried the latest Catalyst Drivers for Linux for 64 bit including Beta and still cant get this working. I dropped the driver down to AMD Catalyst Driver 11.3 as I read that series 5xxx AMD Cards need the older drivers to work. Does anyone have working 5970,5870 cards and resolved this error?

Any advice is much appreciated to resolve this issue.

-gpu-map      Map OpenCL to ADL device order manually, paired CSV (e.g. 1:0,2:1 maps OpenCL 1 to ADL 0, 2 to 1)

Maybe

I have a computer that had two 7870 XTs in it, later I have added one 7770 and after a while replaced it with regular 7870, after I bought some more riser I have added 7770 again.

So right now I have four cards in following order:

PCI-E x1: 7870
PCI-E x16: 7870 XT
PCI-E x1: 7770
PCI-E x8: 7870 XT

Everything works fine, except that GPUs in cgminer and their details are all mixed up, for example one of my 7870 XTs shows temps from 7770 etc.

When I run cgminer -ndevs I get:


So you can clearly see that cgminer says that GPU3 is Tahiti (7870 XT) and then later displays that GPU 3 is 7770, can it be somehow reordered and saved to a config file, so sensors and auto-gpu would work?

You can't.  Use multiple copies of cgminer, one per blockchain.

How do i config GPU to scrypt mining and a FPGA to SHA mining?

easy as, how do i config scrypt mining device 0 and SHA mining a device 1.

Make a decision bro. Indecisiveness isn't attractive.

sorry kano i was hoping that meant you cant mine different coins at the same time, which was never my intention. my apologies. I suppose i will setup something to ping my current pool and if packets lost restart cgminer with different config.

As I tweak settings for --scrypt on my system with a 7970 and a 7950, the 7950 is routinely outperforming the 7970, which is odd enough. But also I've started watching the "U" and "WU" and comparing against MH/s. 
Ultimately it's the U and/or WU which count, right? Do they always match the total system MH/s linearly? I'm seeing some variance but I haven't totally figured it out, yet. What's the main thing to watch?

i.e. as per line 3 of the README, no you can't mine multiple coins.
You'd have to stop cgminer and restart it with the different coin.

Decide which coin you want to mine and go with it.

I've been searching for an answer to this for a bit now and im not sure how to accomplish the following.

with the fallback option, lets say i was mining litecoins on pool x with the scrypt flag (obviously) and wanted to fallback to a bitcoin pool if the litecoin pool was down. What would be the best way to accomplish this. is there a way to disable the scrypt flag once its been launched with scrypt or what do you guys think my best solution would be to have something like this work. another option i could do if possible is change it through the api but im not aware of algorithm changing being a cgminer api option. thanks in advance guys.

I installed the driver over a week ago.  This is the interim of what?  The solution is not changing the driver? or rolling back the driver?

Usual story, you've likely changed your driver in the interim.

--gpu-platform 1 ?? 

Tried to use Cgminer 3.1.1. and it crashes on startup.  Same .bat file as I'm using with 3.1.0.  I removed "--gpu-platform 1" and it boots normally, although it boots into platform 0, which is my CPU i5 processor.  GPU-Platform has always worked.  Wondering if it's broken in the latest build?

Latest build is throwing an exception on start up. 
Running on WinXP.
Mining with BFL BitForce FPGA Singles (not SC)

I have a cmd file that fires cgminer up and specifies which com ports to connect to.
CGMiner rolls through testing all the ports to run on icarus, avalon, then BFL SCs, then it crashes.

Faulting application cgminer.exe, version 0.0.0.0, faulting module cgminer.exe, version 0.0.0.0, fault address 0x0005b469.

Is this in response to my pool connection errors? The thing is, I was having the pool connection errors before I added one more card and before I tried new drivers. The errors started with the exact same settings I had been using for almost a week with no problems at all. All of the changing drivers, etc. was after many failed attempts to communicate with the pool correctly. The HW errors, when the pool actually connects, only lasts the first minute or two, be fore all three cards are runing 500KH/s to 700KH/s depending.

 Yes, running Windows 7. What's curious is the 7970 in the first slot keeps chugging right along while the 7950 in the second slot sits DEAD.
