My Ubuntu 12.04 system hung. I had to force power it off. It now boots only into console mode.
On booting, I catch a glimpse of "cannot write bytes", but there is nothing in the boot log.
I have tried booting recovery mode from grub, and when I run graphics in failsafe mode, I'm getting a Screen(s) found, but none have a usable configuration.
I have read this post, and applied the instructions, but I still don't boot into the desktop. I have looked in syslog and cannot find an obvious culprit.
unity --reset fails indicating a bunch of errors, including D-BUS not running and "did I just try to reset in a tty".
I like to think I can diagnose a lot of Linux problems, so I am asking more for things to check than necessarily an answer to fix this, but an answer would also be helpful.
