I've just installed LinuxMint XFCE, which seems to be still a bit to heavy for my hardware. Thus, I'm thinking about LXDE installation and wonder if a new Linux installation is necessary/advised in such case.
The question is: How to switch easily?
The additional questions are:
a) is it necessary to remove the XFCE packages or both DEs may be installed at the same time?
b) is there any way to simply switch between DEs (i.e. have both DEs available and boot with DE selected each time)?
c) are there any performance consequences of having more than one DE installed? it means: is clean LXDE installation faster than Linux with 2 separate desktops?
