I've hosed my system so many times, I figured one more wouldn't hurt.
I have a plain vanilla HP a6720y (AMD Phenom X4, 6 gigs of ram).
I started with wanting to run with a KVM switch hooked up to my XP box and migrate the physical box it
an XP vm inside of my 64 bit Linux. Simple enough? right?
Well, new linux kernels hate old usb kvm switchs, NVidia 180 drivers didn't recognize my Nvidia video card correctly
to start with. To come to this conclusion I went through Mint 6, Ubuntu, OpenSUSE, Sidux, Mepis, Sabayon.
The first thing that dropped was KDE + Compiz. Apparently there are hiccups there (at least with my hardware). I wasn't
sure which was the culprit.
Then a trip to the Computer store for a new kvm switch.
So then I went through the above list again (using Mint 7). By now I was hooked on gnome;)
Mint 7 and Ubuntu Jaunty were close, but apparently the kernel was prone to freezes, which really killed me
Sidux and Mepis seemed stable, but no real gnome option. I had a core2 quad at work where I had already taken Jaunty to Alpha 3 (but installed the Mint 7 theme). At home, I re-installed Mint 7, ran for about a week, then started getting the freezes. So I threw caution to the wind and "fixed" sources.list to point to Karmic... By this time, if I hosed the system, so what, I can install them in my sleep
What brought me to Debian was one-stop shopping.
What brought me to SID was apt-get update && apt-get dist-upgrade.
