You have likely found the kernel used with Ubuntu Studio is compiled
differently than that used with Ubuntu or Kubuntu. One of my machines
runs Ubuntu Studio but the use is very limited for me. It is no problem
to set-up a machine that is running Ubuntu for the KDE desktop but with
Studio many conflicts exist with programs.
I would suggest downloading a copy of Kubuntu and installing it on a
different partition. Have you noticed that Studio has limited options
for word processors and many of the programs that are pre-installed on
the other Ubuntu distros? I believe that the kernel is called a
premptive kernel, but that is a guess as I researched it a few years ago
and my memory is questionable. Anyhow you don't want to mess with the
kernel because the time slices are much different than is in the other
distros.
