-.Cd "pnozz0 at sbus?"

-.Sh DESCRIPTION
-The
-.Nm
-is a color frame buffer with graphics acceleration, embedded in the
-.Tn Tadpole SPARCbook
-3GS, 3GX, 3TX and 3XP
-laptops.
-It is based on the

-RAMDAC.
-.Pp
-The

-but makes its functions available via the internal
-.Xr wsdisplay 4
-interface.
-.Pp
-If the
-.Xr tctrl 4
-device is also configured, the
-.Nm
-will be powered down when the lid of the laptop
-is closed or the screen is blanked.
-.Pp
-The
-.Nm
-driver supports hardware acceleration to erase the screen and scroll text.
-.Sh EXTERNAL VIDEO
-If the
-.Xr tctrl 4
-device is also configured, the external video output will be enabled when
-an external display is connected, even if the laptop lid is closed.
