To be frank: "interesting project" is quite bold a description for
installing more than one DE in Linux. It would be "interesting" though,
if the US-packages would fail to run OK in KDE, Fluxbox UNITY, you name it.

So if you got the time, and if you do not mind please allow me to point
your attention to other things, that my or may not be most interesting too:

Mon May 13 17:50:27 2013: JACK server starting in realtime mode with
priority 10

"/org/freedesktop/ReserveDevice1/Audio2": A handler is already
registered for /org/freedesktop/ReserveDevice1/Audio2

Mon May 13 17:50:28 2013: ERROR: JackServer::Open failed with -1
Mon May 13 17:50:28 2013: ERROR: Failed to open server

To have a Ubuntu Studio, that can in fact always start Jack on supported
hardware under any DE you like, would indeed be a most interesting thing
to be achieved I dare to think.

best regards


Ahhh: OK, OK: if you can *promise*, that you can make the above
mentioned failed to start kind of thing disappeare for good, I would
provide a nice US-Menu and some documentation too for running US under
KDE. And half a dozen Wallpapers....
