I just have a question regarding the installation of linux mint on my workstation. Just as a brief history, I already have Elyssa installed and it is working beautifully. However, I often get problems on my workstation when playing movies (the screen just goes blank) and then I have to manually power off the machine and then reboot. This causes the fsck to come in for the rescue. Now, my file system got messed up once and it managed to recover from a live cd. The smart thing i did was that I placed /home and / on separate partitions. So, I wasnt afraid if my Elyssa spiralled all the way down. Yet, I then remembered that I had tweaked my workstation with different themes and other great stuff which I really love. I believe that this is not saved in my /home partition but rather under /etc and other places. I want to keep all of that stuff in tact.
Basically, I am asking how can save my stuff all of it i.e. ranging from personal files to OS tweakings in such a way that when I do reinstall linux mint I would not encounter any problems. I have heard of people distributing their file system across many partitions like /boot, /home, /etc, /.
