I burned a bunch of Linux Mint variants to DVDs and USB keys and gave it another go this past weekend. Once again I was unable to get the LTS version to install. I quickly gave up on that version and tried Linux Mint Debian. For some reason that installed with no issues and supported all of the hardware right from the beginning. I'm sticking with that for now as the default OS for this machine (although Windows is still hiding in the background via GRUB).
I was impressed that random customers jumped onto the machine within minutes of my setup of a Desktop account and had no problem using the system. I asked and they'd never used Linux before, so that was reassuring.
Anyone else use LMDE? I like the idea of the rolling installations, so I won't have to reinstall the system. Any major Cons?
