I mine on Ubuntu not Mac so I don't use homebrew for bfgminer. (I just use a Mac to check status.)

Anyway, problem solved -- I was running the older version by mistake.

I use a Macbook to ssh into an Ubuntu rig, and I'm still seeing this bug in the Mac's display, even after building from the latest git. Not a big deal since it's still hashing away. Is there a way to rebuild *with* unicode support?

Has this fix made it to cgminer 3.0 yet? I'm experiencing the same problem in Ubuntu -- no menu options displayed and keystrokes ignored after I specify a config file at startup.

I am experiencing a similar problem with the HD 7850. Did you ever figure out how to install the drivers?

Thanks, there is nothing here about magic cookies but I did get it working again by following the instructions for SSH X11 forwarding on the LinuxCoin wiki.

I'm experiencing a recurring problem that I hope can be addressed in the next version of LinuxCoin: after one of my two GPUs freezes and triggers a reboot, LinuxCoin (0.2 final version) fails to identify either card and I have to reinstall everything from scratch.  My cards are not seriously overclocked (5850s @ 840 Mhz) and one or the other freezes about once a day.  Having to do a complete reinstall every day is not my idea of productive mining.

In case it helps with diagnostics, below is the error message I get when I try to run Smartcoin after a LinuxCoin reboot.  It appears to be related to OpenCL.

I ended up reinstalling everything and Smartcoin now works well for me in LinuxCoin.  The first installation turned into a mess and I decided to start afresh.  Thanks for the suggestions!

Thanks gnar1ta$ for the suggestion - it worked!  Now I'm experiencing another problem: OpenCL won't recognize my GPUs; only the CPU shows up when I run clinfo.  I have agreed to the icd license and even downloaded and extracted the icd-registration file again just in case, but it made no difference.  Would reinstalling the SDK help?

(I have posted a similar question on the Smartcoin thread but it seems more appropriate here; sorry for the seeming double-post.)

I am having trouble getting Smartcoin to automatically identify my GPUs.  I just set up LinuxCoin on my machine so it is most likely related to that.  (Smartcoin had been working beautifully on my HDD before the switch to LinuxCoin.)  This is the error message I get when I try to add the GPUs manually from within Smartcoin (hey, it was worth a shot) and then start mining:


(The last couple of lines appeared when I tried re-installing Smartcoin.)

Also, I set up a simple profile yesterday and it seems to have disappeared; perhaps it's not saving to the persistence file?

I would appreciate guidance from folks who have got Smartcoin running successfully on LinuxCoin.  Thanks!

UPDATE: It turns out OpenCL is not identifying my GPUs at all; only the CPU shows up when I run clinfo.

I can't get LinuxCoin to boot on my machine -- only a blinking white cursor on a black screen is displayed.  I suspect this is a display problem rather than a LinuxCoin-specific problem.  Is there a relatively simple way to resolve this, without having to boot into recovery mode or the GRUB menu (the recommended solutions for display problems)?

If there is a way to set up LinuxCoin through SSH and avoid the whole display issue entirely, I'd be more than happy to do it that way.  So far I haven't come across any guides for that.

Thanks for your help.

Thanks -- I found it by searching through the thread.  I know you've already got tons on your plate, but it might be helpful to new users to include that info in the first post.

What is the default miner output format string?  I tried editing the format string and ended up erasing it entirely.  Weird characters appeared every time I pressed one of the arrow keys or the delete key to move the cursor.  Now it's totally blank and I can't see a thing.

I don't know, but that's the stable version number that was available for update.  I just updated to the experimental version to get rid of the error messages. Is it possible to revert to the last stable version, or am I stuck with experimental now?

Update isn't working for me -- it says the current stable version is 425 (I'm now on r449).  Do I need to completely uninstall and reinstall?  And is there a way to reinstall without wiping out my database?

I just updated to r449 and I'm getting a bunch of syntax error messages:


I froze it in mid-stream so there are probably more error messages along these lines.  Shares are still being accepted, though.

ALERT: the wallet address associated with my account recently changed without my input, and now my confirmed rewards are 0.  (Previously they were 0.04 btc).  Not a huge amount of coin, but still...

Here is the offending wallet address: 14WosrXn3jMZ5frLbxgs4URCRvvfLYQBMq.  I just changed it back to my real address, and I've updated my password, too.

(I guess someone finally cracked my Mt Gox password.  I thought it was relatively secure, but perhaps not.  Boo!)

I just discovered what appears to be a bug: I added a new worker and then edited its pool (but didn't actually change any data; just wanted to make sure it was configured properly).  That new worker/pool was automatically ranked first in the list of Failover profiles even though I hadn't changed anything about the Failover order.  I had to manually edit the Failover order back to what it was before the addition of the new worker.

On an unrelated note, I would also like to know how to launch smartcoin automatically at system startup.  What lines need to be added to which files to accomplish this?  Can I stick something in /etc/init.d/rc.local (which is how I started miners before smartcoin)?

The fix seems to be working for me -- stale rate down to 1.3% after mining overnight.

Funny, the error messages seem to have disappeared, but just in case they decide to reappear, here's the output that you asked for:


Thanks for implementing the failover profile so quickly, btw.  Much appreciated!

Is there a way to freeze the status screen to read the error message?  Otherwise I have no idea if it's harmless or critical.  According to smartcoin my GPU is merrily hashing away and shares are being accepted, but with that error message I'm not entirely confident that it's working.
