I just upgraded to 12.10 and the upgrade process hung after reboot. Instead of the usual purple loading screen, I get a low res black with yellow dots screen which does not go away. Or I get the low res purple screen that eventually goes to a terminal.
Startx will get me a desktop without an interface, but I can start a terminal from there.
apt-get update then
upgrade, which upgraded a few packages (almost all
libreoffice stuff) but this did not change anything.
I've also tried
mv xorg.conf axorg.conf thinking the display settings weren't set. This did nothing.
Any ideas? My next step is installing from a live cd. Will I be able to fix the upgrade this way, or will I have to reinstall?
