That's the message I get when starting bfgminer. It then goes on to load and run but using only CPU's.

I ran "bfgminer -D -T -d?" and this was the output:

Code:

I'm running Ubuntu 12.04LTS with 3.2.0-38-generic-pae #61-Ubuntu SMP Tue Feb 19 12:39:51 UTC 2013 i686 i686 i386 GNU/Linux

Hardware is an Acer Aspire 4752G laptop with Nividia GEforce GT 630M graphics card.

bfgminer version is 3.1.4

Any suggestions please?

Completely new to Bitcoin. Just installed Multibit 0.5.13 on Ubuntu 12.04LTS.

In the debug log it says:

I do have Tor running but I don't think that should affect anything, since I believe this uses the native connection.
Also DNS resolution generally on the machine is performing fine.

Any ideas please?
