Did I miss something? I'm using Linux Coin 0.2.1b

//BTW: How many GPU LinuxCoin can support? I'm going to plug 7 5850s, now only 5 is ok.

[drgr33n]

xhost didn't allow you to take control of the screens. I'll look into this now. If your using persistence Just add

Code:

xhost +
chmod uog+rw /dev/ati/card* 

to /etc/init.d/gdm just before the exit 0; so it looks like this

Code:

  ;;
  *)
        echo "Usage: /etc/init.d/gdm {start|stop|restart|reload|force-reload|st$
        exit 1
  ;;
esac
chmod uog+rw /dev/ati/card* 
xhost +
exit 0

and reboot for now. I will look into this in a while.

[makiet]

Thank drgr33n

I'll try it and report here.

But how about my other question: How many GPU LinuxCoin can support? (The maximum GPUs can mine in one Linuxcoin machine?)
6 or 8 or 10?

Not sure never tried top overload but I would of thought as many as you can cram into one machine.

[makiet]

I heard there was a limit GPU OpenCL can support depend on OS.

OS can detect as many as I plug in. But on Windows, I'm sure 100% I can only mine with 4 GPU.

But with Linux, someone said 6, someone said 10 (Ubuntu).

[sharky112065]

Are you still coming out with a release version this week? If you say no, guess I will just have to use 0.2.1b and live with the bugs.

In Ubuntu 11.04, i mined with 8 cards on MSI big bang marshal mother board. 4 * 5870 & 4 * 6970.
So, i am sure In Linux you can mine with 8 cards that too different series.
Many says 11.6 catalyst allows Windows to mine with 8 cards, but it didn't work for me. May be if you use same series & cards, it may mine.

Like I said I've never looked into this I will have a bit of a read up later.

Should be ready by mid / end of the week.

Is anyone using GUI miner?  I was using it for a while but ssh is more stable than vnc - especially when straining the GPU for mining.  Just seems like a GUI interface may be easier for a lot of people who are unfamiliar with linux.  It was for me anyway.  May be something to think about adding???

I've been fiddling with it to no avail so far in LinuxCoin.

I read where someone got it working using wine but so far I have failed to do so

It would be very beneficial to my efforts to educate my peers to have it running as the linux command line generates instant hostility whenever I mention or show it.

So for now I have to start my show and tell in windows to show the GUIminer.

I'm sure others can improve on this but this is how I installed it:
- Use Synaptic or apt-get to install python-wxgtk2.8 (I just searched python wx in Synaptic and clicked the box)
- in root terminal

Code:

git clone https://github.com/Kiv/poclbm.git

(this will create poclbm directory so don't be in /opt/miners/ when you run it)

- cd into the poclbm directory you just created and run

Code:

python guiminer.py

I have no idea how to make an icon or run it without a terminal window but it's a great program for beginners, as long as you're not using remote access.

Great post !!! If anyone has little gems like this please put them on the wiki !!!

[V4Vendettas]

Just wanted to say to say thank you thank you thank you.

Without this thread and the op taking the time to do all he has done my mining would have died b4 it had a chance to come alive.

2 rigs up and running with this now and once I have a few more will defo donate 

Lol 3 weeks ago I didnt even know what linux really was and now look at me go.

Anybody found a way to set Powertune via line command instead of AMDOverdriveCtrl for multiple adapters?  I found this, but not sure I can run/compile it under Linuxcoin:

@krumplee: how do you use this undocumented function?

Download ADL SDK from http://developer.amd.com/Downloads/ADL_SDK_3.0.zip
It is enough to copy adl_sdk.h into /usr/include

Save the following code as powercontrol.cpp

Code:

#include <iostream>
#include <cstdlib>
#include <adl_sdk.h>

using namespace std;

extern "C"
{
    int ADL_Main_Control_Create (ADL_MAIN_MALLOC_CALLBACK, int);
    int ADL_Adapter_NumberOfAdapters_Get(int *);
    int ADL_Overdrive5_PowerControl_Set(int, int);
    int ADL_Overdrive5_PowerControl_Get(int, int *, int *);
}

void* __stdcall Alloc ( int iSize )
{
    void* lpBuffer = malloc ( iSize );
    return lpBuffer;
}

void __stdcall ADL_Main_Memory_Free ( void** lpBuffer )
{
    if ( NULL != *lpBuffer )
    {
        free ( *lpBuffer );
        *lpBuffer = NULL;
    }
}

int main()
{
        int adapters, a=99, b=99;
        if(ADL_Main_Control_Create (Alloc, 1) != ADL_OK)
        {
                cout << "ADL initialization error!" << endl;
                return -1;
        }
        
        if(ADL_Adapter_NumberOfAdapters_Get(&adapters) != ADL_OK)
        {
                cout << "Cannot get the number of adapters!" << endl;
                return -1;
        }
        cout << "Found " << adapters << " adapters" << endl;
        for(int i=0; i<adapters; i++)
        {
                if(ADL_Overdrive5_PowerControl_Set(i, 20) != ADL_OK)
                {
                        cout << "Failed to set " << i << " power control" << endl;
                        return -1;
                } else { cout << "Value set for " << i << endl; }
                
                if(ADL_Overdrive5_PowerControl_Get(i, &a, &b) != ADL_OK)
                {
                        cout << "Failed to get " << i << " power control" << endl;
                        return -1;
                }
                cout << "result: " << a << "%, b: " << b << endl;
        }
        return 0;
}

Finally compile:
g++ -DLINUX -o powercontrol powercontrol.cpp -latiadlxx

Has anyone else run into these problems with SmartCoin and LinuxCoin together?  I tried the SmartCoin forum, but the developed said he'd never seen a problem like this.

I am running LinuxCoin 0.2b from a SSD with /home installed on a different partition.  I have difficulties immediately when installing SmartCoin.

When I try to install SmartCoin from either ssh or using a vnc client, I get the below message before being asked for root permissions.

Code:

Then I get this.

done.

Then it throws up the same SQlite header and source version mismatch error dozens of times and continues to give the same error when trying to auto-detect the GPUs and miners.

Locating the SDK path automatically works just fine.

If I decline the auto-detect and later manually try to add GPUs and miners manually, I get the following

Should there be an associated block chain that distributes linuxcoins via mining?

[makiet]

Hi,

I want to run my mining script at startup. I'm using Linuxcoin 0.21b persistent on a thumb drive.

I put my script file (miner.sh) in /etc/init.d directory and used update-rc to register it. But nothing happen when linuxcoin finished booting.

I also tried to put the script in to local.rc but no luck.

Please help.

If I run the miner.sh file in the root terminal manually, it run perfectly.

Please help me to resolve this problem.

Should compile ? You should try it out and let us know. If it does you or I could add it to the wiki.

Depends how you are mining. If your solo you will need to download the blockchain. If your in a pool then no.

Please help me to resolve this problem.

copy and paste the following into a text file and call it mining.desktop

Code:

[Desktop Entry]
Name=start-miners
Comment=Simple script to start my miners
Type=Application
Exec=/path/to/youscript.sh
Terminal=false

Move that file into ~/.config/autostart and make your script executable.

Code:

mv mining.desktop ~/.config/autostart
chmod 777 /path/to/yourscript.sh

Reboot and your good to go. The reason your scripts not working when added to sysvinit  is because your cards haven't been initialized until LXDE has started.

Got to say I've never experienced this before. I can confirm the smartcoin is working great in 0.2-final and I'm working with the author to add additional features to smartcoin/linuxcoin. More info to follow.

[Dargo]

I'm mining with linuxcoin and would like to go headless with ssh to an old netbook I haven't been using. Does it matter at all what linux distro I use (aside from finding one that runs well on the netbook)? I'm currently testing linux peppermint, and really like it. This distro is very fast and has 0 installation issues for me. If it is just a matter of personal taste, I'll probably go with this. But I would appreciate anyone pointing out features other distros have that might make them better for my purposes. For example, is there any advantage to just running another copy of linuxcoin?

Also, is it possible to ssh (or something like it) directly to another computer by ethernet cable? If so would that be more secure than ssh over the network? I hope these question aren't too pathetically newbish, but, well, I'm a newb. Thanks.
