Here's an odd one I'm running into today after re-burning my USB stick's linux image from a clean copy, pulling in the latest git, compiling and firing up cgminer...
cgminer's interface ignores all normal menu keystrokes (p, g, and so on), UNLESS I neglect to specify a pool in the config file, in which case it works normally because it had to accept keyboard input to allow me to set the pool credentials. I can use ctl-c to kill it and get back to a prompt, no problem. I just can't adjust settings while cgminer is running.
This is latest git pull as of "Thu Apr 11 13:31:17 2013 +1000".
Found this bug at last and it should be fixed in git master now, thanks.
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.
