=46rom reading the radeon man page, it sounds like I want mergedfb in clone=
=20
mode.  But as I'm a total noob, I'm not exactly sure.  What I'm looking for=
=20
is to have the same display on both the laptop and the external display. =20
However, I'd like the resolution of the thinkpad display to stay at 1024x76=
8=20
and the external to be at 1600x1200.  It sounds like this can be done with=
=20
the mergedfb option, where I could have two different viewports of the same=
,=20
shared buffer..but at different resolutions.  At the same time, I don't wan=
t=20
to be scrolling around, pushing the viewport to the extended size of the=20
larger external display on the thinkpad.

To turn on MergedFB, I added:=20
 Option  "MergedFB"  "On"
to "Device" section.  I'm unsure what else to do, or what Virtual keyword=20
settings should be to get what I want.

=46rom what I described that I would like, does using the merged framebuffe=
r=20
make sense?

Thanks,
Shaw
