I just try to execute cudaminer via: screen -dm ./cudaminer
And this doesn't work yet...

And of course, other test, with other apps - are successfull
(I have done some tests before, with top for example, please see below)

Maybe it's some strange cpuminer/operating system issue?
OS is Kubuntu 13.10 64bit: http://www.kubuntu.org/getkubuntu  (if you could check)
