The supper view window is seperate from the XDRIVER.

No.

Run the tcltkgrass startup script.  This will start grass and bring up your menu bar.
Pull down the Display menu and select "Open a super view".  This should start a seperate
window titled .v1.  There should be a blank graphics portion and then a portion to the left
with several buttons on it.  Press the top button that looks like a stack of papers.
This will open a spatial layer window where you can select the map, map type, mapset, etc...
Press add layer to select a map and then press apply to actually display the map.

Hope this helps.  Beware though, this window has crashed on us several times while playing.
