If you're going to experiment with adding additional desktops or window
managers (or even new applications that require extensive libs or other
changes to your existing system) I find it helpful to back up my
existing system first. On a regular basis, even if I make no significant
changes to my installation. I use the command line utility dd to make an
image file of the disk partition containing the system I want to back
up, along with that hard drive's partition table. Thus:
dd if=/dev/sda of=Ubuntu.boot.mbr bs=512 count=1 #(for the partition table)
dd if=/dev/sda1 of=Ubuntu.img #(for the partition containing my main
I keep my HOME directory on a separate partition of that first hard
drive as well as reserving two other partitions of equal size to the
first partition on that drive (a WD 120 gig Sata). That way I have two
extra partitions to use to test new distros as they come along. All
three installations can use the same HOME directory and files. If I need
to remove either a distro being tested or restore the main system after
I screwed something up, I have a known working copy of my everyday
working system ready to reinstall simply by reversing the dd command thus:
dd if=Ubuntu.img of=/dev/sda1
Keeping the backed up image on a separate physical drive (in my case a
250 gig WD Sata) also keeps it safe if and when that first hard drive
goes poof. The above dd commands are predicated on my using a USB or DVD
live system to log onto that 250 gig WD, which contains the image files.
Hope some or this helps.
