I second that. However, by default, xpra and GNU Screen are not aware of 
each other. To connect to xpra from within GNU Screen, you usually need 
to set the DISPLAY environment variable manually. I have described a 
solution that automates this, so that GUI applications "just work" from 
within GNU Screen and also survive a disconnect:
