Ethereum: cg Miner not starting and showing error «Error Opening Terminal: Dumb»

Are you one of the millions of Ethereum users who rely on mining as their primary source of income? Unfortunately, we’ve all been there – stuck in a no-win situation where our cg miner won’t start. But don’t worry, I’m here to help!

In this article, we’ll address the problem and provide step-by-step solutions to get your cg miner up and running again.

Why won’t my cg miner start?

Before we dive into the solution, let’s quickly go over why your cg miner might not start. There are a few common reasons that can cause this:

  • CGminer configuration issues

    – Make sure you’ve updated the CGminer configuration file (e.g. config.txt) with the correct settings for your Ethereum pool.

  • Terminal Environment Issues: Make sure your terminal is properly configured, including the correct path to the CGminer executable.
  • Resource Constraints: Lack of CPU or memory resources can cause the cg miner to fail.

Solution 1: Check CGminer Configuration

Try updating your CGminer configuration file (e.g. config.txt) with the correct settings for your Ethereum pool:

[pool]

url= Pool=0x12345678

max_workers = 8

Replace with your current Ethereum pool URL and adjust thePool` settings if necessary.

Solution 2: Clean up the terminal environment

Make sure your terminal is clean and error-free:

$ cd /path/to/cgminer

$rm -rf temp files

$ mkdir -p ./config/

This will remove all temporary files generated by the CGminer executable.

Solution 3: Increase resource constraints (optional)

If you experience resource constraints, try increasing CPU or memory resources:

$ setxgbm -w 20000

$ setres -R 6400

These commands will enable XGBoost with 20GB of RAM and increase the default thread pool size to 2000.

Solution 4: Reinstall cgminer

Ethereum: cgminer fails to start with error

If none of the above solutions work, try reinstalling cgminer from scratch:

$git clone

$cdcgminer

$ ./configure

$make

$ sudo make install

This will overwrite your existing installation with a fresh copy.

Troubleshooting Tips

  • Make sure you are using the correct version of CGminer (3.4 at the moment, but check the latest documentation for updates).
  • Make sure you have properly set up your terminal environment.
  • If you are having issues with network connectivity or pool configuration, try restarting cg miner and the pool manager.

Conclusion

If none of these solutions work, there may be underlying issues with your Ethereum pool or CGminer configuration. I recommend seeking help from a more experienced user or the CGminer community forums for further assistance.

I hope you found this article helpful in resolving your issue with your cg miner!
