Re: [gentoo-amd64] Re: Recovering from emerge --prune

[Jonathan Schaeffer]

Hi people,

After having made a real mistake (emerge -P, jsut trust the mnpage,
don't try it), I've got a system up and running again. I followed
Duncan's advice about emerging the allready compiled grub package and
storing the merged packages.

revdep-rebuild finally found that the consitency was OK, so I run now
a full ~amd64 box.

Full ? not completely...

I switched back to Xorg-x11-6.8 because af a strange crash that
happens precisely 30 minutes after X starts. It's all happening like X
would restart and I'm back to my entrance login screen. Weird ...
I still have this problem even with the stable marked xorg-x11. No
significant logs found ... I disabled the proprietary 3D NVidia
drivers, just to be sure.

I don't have much time left before it crashes again, so I'll end it up.

I put what can be seen in /var/log/messages (note the timestamps) :
