Okay, you are using the tpmrun tool. This is a testing and debugging  
tool and does indeed require the graphical console. You need to add at  
least the following to the command line if you want to use it:

   -l con-ux

(Alex B., are there any additional requirements / things to be taken  
care of?)

Btw., stpm-ux will try to use the physical TPM of the host platform  
unless you loaded the kernel module of the TPM emulator instead of a  
real TPM driver (this worked for older versions of the TPM emulator, I  
am not sure about later releases).
