I know there's a section for Sabayon talk, but I made a thread on this for FC6 so I thought I'd do it again for Sabayon.
Took me a while to actually try Sabayon. My "sandbox" desktop that I've mentioned so much lately has a crappy graphics card, and what's the use in using Berly's official distro if I can't use an accelerated desktop? Plus I've been scared off by Gentoo before - a couple months ago I tried the latest Gentoo and didn't even get as far as getting it installed. The only thing harder than that I've ever tried was FreeBSD, and at least I got it on the harddrive (I just couldn't get X to work!) Plus I don't have a DVD burner, and the Sabayon website is not nearly as intuitively laid out as the Ubuntu site - and they don't exactly advertise very well that the mini edition is everything the full version is, minus some little details (like the pre optimized kernels and the SuSE-style kicker) and the server stuff. Alright, so I finally figure out I can use it, and decide - what the hell, it's about time for a reinstall anyway, I'll put it on my laptop and try and get it to play nice with Kubuntu. Well, it didn't play nice. At least not for me. I tried to use the same /home partition I did for Kubuntu, and they tried to read each others config files and it ended up a big mess. I still don't completly understand why it went so bad, but it was definitely bad. So, put in a prayer of thanks that I backed up anything important, and said screw it, I'm gonna just do a fresh install.
And now, my friends, the story gets good. Install goes flawlessly, and almost everything works out of the box (still trying to figure out why my multimedia keys, which are mapped correctly, do nothing and why it recognizes my entire touchpad as a pointer controller instead of the edges as scroll zones - but everything, and I mean everything, else works great). XGL and Beryl get along better with my ATI card than they ever did with SuSE or even Kubuntu. But, damn it, I still can't stand the portage system. And the way it didn't get along so much with Kubuntu makes me wonder just how stable it is. After all, they advertise "cutting edge." I'll still keep a computer with Edgy on it, just in case. I love the community and the philosophies -and Apt - of Ubuntu too much to leave it behind. But I'm gonna give Sabayon a whirl as my primary for a couple months and see if I can still be productive. I've already had a couple issues (the first time I updated and then synced portage, knetworkmanager broke), but I had issues with Kubuntu when I was a newbie, too. Thus far, my personal experience with Sabayon leaves FC6 in the dust, and outpaced SuSE by a good distance, too. My initial experience with it has been better than my initial experience with Ubuntu, but I was also much less knowledgeable about Linux then. It's also miles and above better than my experience with regular Gentoo. I'll probably come back to Kubuntu, or maybe dual boot, especially when Feisty comes out (already tried Herd 2 and 3 - looks awesome, and some of the stuff in the works on Launchpad looks even cooler). But if nothing else learning Gentoo via Sabayon will hold me over until 7.04.
