I am thinking about installing Ubuntu Studio on my new laptop, basically because Jack coexists with PulseAudio "out of the box" which I have found impossible to achieve in a previous installation. Also, it uses the low-latency kernel by default. However, I'd also like to keep using Gnome shell.
Hardware: Lenovo T430.
I have tried
apt-get install gnome-shell gnome-session
but this brings along more than 100 extra packages, some of which I am not sure I really need. In addition, it asks if gdm should be the default display manager (instead of lightdm), however, according to Wikipedia, the former is the newer and better alternative. After keeping LightDM and changing the greeter to use the Unity greeter (the default greeter doesn't seem to recognize the new session types), I can log in to Unity but not to the good old Gnome shell.
This is just a brief summary of several hours of reinstalling Ubuntu Studio and trying to make things work.
What is the most robust path to achieve the desired result -- an installation with a low-latency kernel and working Jack, with Gnome shell?
Install Ubuntu Studio + ???, how to configure?
Install vanilla Ubuntu, add some packages from Ubuntu Studio, how to configure RT+Jack?
This related question suggests installing
ubuntu-desktop, but for 12.04. This answer points to an instruction to add Ubuntu Studio features to vanilla Ubuntu. I haven't yet tried either of these options.
