One of my hash boards dropped; cannot login.  Swear I did not change password.  

HOW TO FIX/RECOVER the password, keeping in mind I know absolutely NOTHING about any version of Linux?

Update:  Had to power-off everything.  Pulled standard unit and full unit.  Re-plugged in everything.  Power on standard unit - standard password - futurebit123 - works on boot up screen just peachy fine.

BUT.

Lockscreen - no joy.  If I had changed the password at some point, there are a few ones I would have used. None of them work.

Been an hour now - full unit is hashing - slush pool reporting it.  Unfortunately, the standard unit is solid red light and it's obvious because slush pool is 1/2 of what it should be.

I should point out the front light on full unit has NEVER worked, but it hashes just fine.  Light on standard unit is solid red.  Prior to 2 days ago, it blinked slowly - it was hashing.

Not being able to get to the dashboard has frustrated my ability to troubleshoot any further.

HELP.  HELP.  HELP.

Oh, BTW, I have 2 of the FutureBit supplied power supplies.  When I WAS able to see the dashboard, both units were pulling within a couple watts of each other.  Unfortunately, 1 power supply "tubo's" its fan about every 2-3 minutes.  Very noisy - stays that way 5-10 seconds - then resumes back to normal.

I've tried swapping power supplies (between standard and full unit) - regardless of what this one is powering, same EXACT thing happens.  Is there some way (an internal POT or something) that can be adjusted up 2-3 degrees to stop this?


Thank you.
