Replace Unity with LXDE?

[John Hupp]

I have been trying very hard for several months to get a Lubuntu + LTSP 
network running smoothly, but have run into one problem after the next 
with various applications not working right in this environment.  I have 
filed the bug reports and worked with the Lubuntu mail-list support, but 
success is not yet within sight on half or more of the issues despite 
everyone's efforts.

I also have an Edubuntu + LTSP test network, and I observe that a number 
of these problems don't appear on it.

However, Edubuntu is a MUCH slower performer.  I also don't need the 
educational array.

I understand that in substantial part, Lubuntu is Ubuntu except with 
LXDE instead of Unity for the desktop environment, and add to that a 
selection of lighter-weight apps than many of the selections for 
Ubuntu.  (And Edubuntu is Ubuntu + the educational apps.)

Not only that, but Ubuntu has a distro integrated with LTSP, and also 
has LTS support.

So I'm now wondering if I could get Lubuntu-like performance and fewer 
problems to deal with by starting with Ubuntu, replacing Unity with 
LXDE, and installing some of the lighter-weight apps.

Or is it likely that most of the app problems will follow LXDE?

If LXDE-replaces-Unity-on-Ubuntu seems like a solution, how hard is it 
to do that?

Or if that is a bona fide guru exercise, is there another change that 
will get me most of the way to the goal?
