Hmm...I too am totally new to Gentoo/Sabayon, tho I've used lots of Debian
and openSUSE. So, clearly I too do not know Entropy from a hole in the ground.
I did my first installation of Sabayon yesterday, from the 4.1 K (KDE-4) Live-DVD.
All that part went fine, got wifi-adapter working on the next reboot, installed 'ffmpeg'
and 'wine' and figured I'd try to read a little and try to get my head around 'Entropy',
'emerge', 'ebuild', and any other 'E' words.
So, after perusing the wiki, I concluded that where I once would say:
'apt-get update' followed by 'apt-get upgrade'
that I now should try to say:
'equo update' followed by 'equo world --ask'
to bring a just-installed system up-to-date.
I'll bet you know where my story goes from here. I just read a thread that
sounds VERY SIMILAR to my story: the result being that when I boot my
system now, I get no explicit errors, but it comes up just to run-level-3
and invites me to do a console login.
Based on my knowledge of other (non-Gentoo-based) distros, I suspected that
X-windows or my nvidia-graphics driver might have been involved in one of the
couple hundred of updates that got executed in that two-hour 'update' of the
installed software. But, xorg.conf hadn't been touched at all, based on my
browsing of the dates of the various xorg.conf variants lying around in '/etc/X11'.
[Just for grins, I tried switching back from 'nvidia' to 'vesa', but that didn't
change the symptom.]
And, near as I can tell, none of those couple-hundred updates involved updating
my kernel. It still says 2.6.29-Sabayon, and /boot/grub/menu.lst didn't get
touched by the updates either. Yet, this breakage symptom SEEMS to
resemble symptoms found in other distros after the kernel changes, but
some drivers didn't. [Yet, I didn't need to BUILD any drivers during/after
my installation, so I don't understand what got upgraded that borked things.]
So, why did it break, what do I need to learn about software updates
on Gentoo-based distros, and what run-level-3 incantations to I need to
invoke to fix it? [I'm reasonably comfortable at run-level-3 with 'vi' and
the command-line, etc.]
