I know this is an old thread, but it sounds like you guys might know what is going on.
I'm trying to set up 2 video cards with one monitor on my Linux Mint 14 system using cgminer.
1 card was working just fine, Installed the second card and linux would no longer boot. Reinstalled the newest ATI drivers 13,1 and the computer booted.
My cinammon desktop is gone and there is 2 of everything on my taskbar. I believe it's displaying 2 of everything since it is set up to dual monitors??
Good news is, cgminer is recognizing both cards.
This is what my xorg.conf looks like

So what do i need to fix here to get cgminer recognizing both cards while only using 1 monitor and not messing up my desktop environment?
Topic: 5970 2nd GPU woes (Read 6459 times)
TheManOfTown, I think it's not necessary to disable Crossfire. But on Windows 7 you have to have both GPU cores attached to a monitor or a dummy VGA.
For me the working solution was to Use Diablo miner and have Catalyst Control Center not running (I disabled it with msconfig.exe).
For me the working solution was to Use Diablo miner and have Catalyst Control Center not running (I disabled it with msconfig.exe).
I have the exact same problem, but I am running windows 7. I have a dual 5970 rig, and the 2nd gpu on the 2nd card will just not mine. It starts for a little while, and then it shuts down.
I read about the solution in this thread to disable crossfire, how is that done in windows 7? I tried to use Catalyst Control Center to see if I could figure it out, but it was not obvious how to do it. Anyone knows anything about it? I will pay 10 BTC to whoever will help me figure this out and let me have a working solution.

a little bash script to start up mining. Feel free to change what you like to suit you 
These are handy for starting mining while physically at the miner or sshing into it You could tie them all up into one script if you like ?[/code]
Code:
#!/bin/bash
# poclbm starter for linux by drgr33n.
# Remember to set your vars !!
USERNAME=""
PASSWORD=""
URL=""
NVIDIA_FLAGS=""
ATI_FLAGS=""
CPU_FLAGS=""
i=0
if [ test !-f ./poclbm.py ]; then
echo "You need this file to be in poclbm's root directory !!";
exit;
fi
while read -r; do
if [[ $REPLY = *VGA* ]]; then
arr[i++]=${REPLY##*: }
fi
done < <(lspci)
for k in "${!arr[@]}"; do
printf 'GPGU %d is %s\n' "$((k+1))" "${arr[@]%% *}"
printf 'Starting poclbm on GPGPU %d\n';
echo $k;
sleep 15;
if [ "${arr[@]%% *}" == "NVIDIA" ]; then
DISPLAY=:0.$k ./poclbm.py -d $k -u $USERNAME -p $PASSWORD -o $URL -P $PORT $NVIDIA_FLAGS&
echo "Done.";
elif [ "${arr[@]%% *}" == "ATI" ]; then
export GPU_USE_SYNC_OBJECTS=1;

echo "Done.";
else
./poclbm.py -d $k -u $USERNAME -p $PASSWORD -o $URL -P $PORT $CPU_FLAGS&
echo "Done.";
fi
done
Code:
And here's a little script I use to check my balance and temps etc.
[code]
while true; do
DISPLAY=:0 aticonfig --adapter=0 --od-gettemperature | tail -n1 | awk '{print "Current temp: " $5}' ;
DISPLAY=:0.1 aticonfig --adapter=0 --od-gettemperature | tail -n1 | awk '{print "Current temp: " $5}' ;
DISPLAY=:0 echo $(aticonfig --odgc | grep GPU);
DISPLAY=:0.1 echo $(aticonfig --odgc | grep GPU);
# Next lines are to check your balance if solo mining
# BALANCE=$(bitcoind getbalance)
# echo -ne "Bitcoin Balance: ${BALANCE}\r";
sleep 35;
clear
done

Thanks! I'm still a little new to getting around in bash. 
I might just start a new thread, but I thought I would try this first.
How to you control your over clocking of both cards to be 920/300?
Is there a way to do it manually? I've tried some of the commands, but ATI doesn't let me go below 900 memory speeds, and that is unacceptable.
I'm using AMDOverdirveCTRL right now, but it only works on the first card.

AMDOverdirveCTRL defaults to the first adapter, you have to manually specify other adapters.
Do AMDOverdriveCtrl --help, it should list a number of adapters.
Look for index numbers that are active and run
AMDOverdriveCtrl -b -i # OverDriveFile (# being the active index number)
The man page is also helpful

Every terminal window you open has a different display number. Any window you open you will need to first execute, you will also need to do this before most commands.
export DISPLAY=:0
Run your poclbm after that and see if both (all) your devices show up in that list.
export DISPLAY=:0
Run your poclbm after that and see if both (all) your devices show up in that list.
Kind of ... to see what DISPLAY a terminal is attached to, inside the terminal you do a
$env
and it will list the environment variables of the shell attached to that terminal ... in amongst those variables is
DISPLAY={something or rather}
When you do an $export you are setting an environment variable (or not if you screw it up).
Some Unices you can also do a $setenv or $getenv also ....
When you do the
$export DISPLAY=:0
you are accessing all the sub displays associated with the root display '0'
0.0
0.1
0.2
... et etc
In ubuntu if you want your terminals to always come up with the DISPLAY variable set to 0 (always referencing root display) you can put this line in the user .bashrc
export DISPLAY=:0
I've found the newer driver fglrx version 11.2 doesn't need the DISPLAY variable to be set to '0' to make all cards available to OpenCL ... DISPLAY=:0.0 sees them all also.
I think it's working now. I haven't seen any invalid blocks since my last post.
What power supply do you have? This sounds like a power problem.
Every terminal window you open has a different display number. Any window you open you will need to first execute, you will also need to do this before most commands.
export DISPLAY=:0
Run your poclbm after that and see if both (all) your devices show up in that list.

ok, thanks moa. I don't need any monitors except for what's required for mining.
I had no idea to use those aticonfig parameters "aticonfig --initial --adapter=all -f",
they generated a completely different xorg.conf than the other two xorg.conf files I've used.
I got two DiabloMiners running, one on each GPU with no loss in hashrate, unlike before.
I uninstalled poclbm's dependencies so I will simply wait and see if any invalid blocks show up.
I set fan to 100. Thanks again.

Do you want/need two monitors or is this a mining rig?
If you want to do just mining, you could unplug one monitor and instead of
$aticonfig --initial
do a
$ sudo aticonfig --initial --adapter=all -f
??
One adapter (GPU) should be assigned to display 0.0 and the next to 0.1 (screens 0 and 1 in xorg.conf).
It seems they are both assigned to the same adapter ... xorg is a pig that shouldn't really be used for assigning computational power of GPU but that is the way it is right now since they are historically graphics cards, not crunchers. Confusing it with trying to be clever graphics power and mining compute node is not the way to go.
If you can get something like the below in your /etc/X11/xorg.conf file, after turning off crossfire and running the "$aticonfig --initial --adapter=all -f" command you'll be in better shape. You must restart after running aticonfig also (only Xserver actually but just reboot for good measure).

I have a 5970 with no overclocking on Debian stable (Squeeze), ATI Stream SDK 2.1 and fglrx 10.9.3.
If I run one of poclbm or DiabloMiner on just the first GPU, either one gets 270Mhash/second.
If I try to run poclbm on the 2nd GPU (-d 2), within 1 minute claims "Verification failed" a large number of times, and exits.
If I try to run DiabloMiner on the 2nd GPU (-D 1,2), it runs for a long time with no errors,
getting 510-530Mhash/second. I use -f 1, because every other value I tried has lower hash rate.
Every few hours, DiabloMiner will display 5-20 lines of "Invalid block found" (on GPU #2) and just keeps hashing.
ArtForz tried to help me with poclbm on IRC but ran out of ideas. His theory is that any sort of verification failed
is due to CrossFire being turned on. At first I just took this at face value and believed it. Is it true?
Here's how I run: I use aticonfig --initial to generate a xorg.conf which utilizes both outputs.
Both monitors show the same screen all the time. Both are on "DISPLAY=:0.0".
Below are the output of aticonfig --lscs and --lsch.
I can get lscs to show CrossFire disabled but it says I need to restart X to take effect,
and doing so causes it to show CrossFire enabled again. I can delete the chain altogether,
restart X, and it re-creates the chain and definitely turns CrossFire back on. This is the best I've been able to do:
$ sudo aticonfig --lscs
Candidate Combination:
Master: 3:0:0
Slave: 4:0:0
CrossFire is enabled on current device
CrossFire Diagnostics:
There is CrossFire Side port connection between GPUs
CrossFire can work with P2P write through peer aperture

I've tried "aticonfig --initial=dual-head". The resulting xorg.conf causes two monitors to show different desktops
and one is DISPLAY=:0.0 and the other is DISPLAY=:0.1. In this case, both poclbm and DiabloMiner
only find one GPU (#1), from either display. I can run two miners (either poclbm or DiabloMiner)
at a time on GPU #1, but only one gets full hashrate, the other gets under 200khash/sec.
Crossfire is definitely disabled completely in the dual-head setup.
Running two copies of DiabloMiner, one one each card, on single-head X setup results in only one instance
with a decent hashrate, the other gets about 2Mhash/s.
Can anyone help here? Are occasional invalid blocks in DiabloMiner normal, or is DiabloMiner
simply failing to check its work as thoroughly as poclbm? Am I wasting
power by mining on GPU #2, and it will never generate a valid block?
Is there a way to verify GPU #2 is functioning properly other than by running mining software?
Is GPU #2 just bad? Should I mine on it anyway? Is there a way to get CrossFire to show completely disabled and mine
using both GPUs? Should I upgrade to sid, with a newer fglrx? Should I try ATI APP SDK 2.4 beta?
Do I need better cooling? I have no idea how to change fan speeds, but I do have
a crappy case with the case off and a desk fan blowing on the video card.
