 Replying to [comment:6 neteler]:

 `d.rast` when `d.mon wx0` is active causes creation of `map.png` in the
 current directory:

 related to this issue something changed in display architecture (probably
 Glynn will know more), now you don't need to start any monitor to render
 data

 {{{
 d.mon -p
 No monitor selected

 d.vect streams --v
 Using display driver <cairo>...
 cairo: collecting to file 'map.png'
 cairo: image size 640x480
 Plotting...
 8554 lines plotted
 d.vect complete.
 }}}

 I would see this behaviour as misleading from the user point of view. In
 GRASS 7.0:

 {{{
 d.mon -p
 No monitor selected
 d.vect streams
 ERROR: No graphics device selected. Use d.mon to select graphics device.
 }}}
