Hi Dan,

kworker, although due to the 'k' at the beginning may give the impression 
that it is related to TDE, it is a thread in the kernel. That's why it 
runs there, even if you login into XFCE.

The only thing where TDE could be directly related to the kernel is if you 
have SAK turned on. In this case, a special 'event' device for capturing 
the keyboard is created there.

Cheers
