Ethereum: cg Miner Fails to Start with 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 dead-end situation where our cg miner fails to start. But don’t worry, I’m here to help!

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

Why is my cg miner failing to start?

Before we dive into the solution, let’s quickly go over why your cg miner might be failing to 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: Ensure that your terminal is properly set up and configured, including proper pathing to the CGminer executable.

• Resource constraints: Insufficient 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 actual Ethereum pool URL and adjust thePool` setting if necessary.

Solution 2: Clean terminal environment

Make sure that your terminal is clean and free of any errors:

$ cd /path/to/cgminer

$ rm -rf temp files

$ mkdir -p ./config/

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

Solution 3: Increase resource constraints (optional)

If you’re experiencing resource constraints, try increasing your CPU or memory resources:

$ setxgbm -w 20000

$ setres -R 6400

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

Solution 4: Reinstall cgminer

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

$ git clone 

$ cd cgminer

$ ./configure

$ make

$ sudo make install

This will overwrite your existing installation with a fresh copy.

Troubleshooting tips

• Make sure that you’re using the correct CGminer version (3.4 at this time, but check the latest documentation for updates).

• Ensure that you’ve set up the terminal environment correctly.

• If you’re experiencing issues with network connectivity or pool settings, try restarting the cg miner and pool manager.

Conclusion

If none of these solutions work, it’s possible that there are 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 this article has been helpful in resolving your issue with your cg miner!
