[Solved] Add/Remove Programs, DEs and Distros
I'm waiting for a hard drive to come in tomorrow and then will be switching over my main system to Linux.
I'm planning to go with Ubuntu, as that distro seems to have the most users and places for me to get help when I run into problems. So I have some general questions:
1) In Windows, adding and removing programs often leaves behind remnants in the registry, data files, DLLs and all sorts of other stuff. I've heard that Linux is not like that, and that if I remove a program, it is cleanly removed. So, for instance, if I wanted to try out 6 different mail clients, I can add and remove programs willy nilly without leaving a trail of crap behind. Is that accurate?
2) What about changing DEs? I'll start with the Ubuntu default Unity, but what if I wanted to try KDE or whatever. Is that a problem? Can I switch among DE's easily?
3) What if down the line I want to ditch Ubuntu and try Mint or another distro? What is involved there? Would I need to format the hard drive and install all the software etc. from scratch?
Edit - thanks for the great answers!
