I just installed Sabayon Linux 5.2_x64.
Several problems arose.
First, I tried running it from the live DVD. It worked (btw, the graphic configuration works but is pig slow, it took so long I left the room and did something else while it finished) but I ran into one problem, after running unattended for several days the monitor was in blanked mode and I could not get it to resume normal mode. Usually, I just move the mouse or press a key on the keyboard and it comes right back but this time I had to reboot.
I tried installing with the Graphical Installer but that failed. After answering all the questions and it started the install, it aborted and wanted to write a dump file to the HD. I tried it several times with the same result each time.
I next tried the Text Installer. That worked. I rebooted, logged in and ran startx. It brought up twm <rant> why do distro developers love twm so much? It is very awkward to use. Fluxbox is slightly better but icewm is clearly superior to either of them, it has a smaller footprint than twm, has very few dependencies, is lightning fast and functions very much like a normal desktop. <end rant>. I was surprised to see twm because I chose the KDE installation.
After fumbling around with twm for a few minutes, (and discovering that mc and konqueror are not installed by default), I exited twm, switched to root and ran kdm. It brought up the KDE login screen and I logged in and KDE loaded.
I had been a Gentoo user for a while but ever since Daniel Robbins left the project, it has deteriorated. 2 years ago I decided I needed to switch to something else. I tried Sabayon then but had to 'jump through hoops' to get it installed and still had some problems with it (I don't recall the details), I decided it was not ready for prime time (yet). In the interim, I've gone through Debian, Frugalware, Arch, Suse, Fedora, Slackware and several others whose names I don't remember.
Lately I've been using Slackware but it has some problems. It is very fast and stable but it no longer supports Gnome so if you use any Gnome programs, you are on your own installing them and it has a limited selection of software so I have to install and maintain 80-100 packages on my own which is very time consuming.
Hopefully Sabayon is mature enough now that I can run it on my production boxes.
