After upgrading to 12.10 64bit, I ran into some issues.
Originally, I installed Ubuntu 10.04, I installed it in windows, since then have upgraded with each new release via the update manager without any problems. I have a Compaq machine with a hard disk partitioned into 3 parts.
12.10 downloaded via update manager, and initial downloading of packages was without problems, however, as it installed the packages, error messages appeared.
The first was one about missing lib files, but I clicked to continue
It continued, and during the restart process, when it was powering down, the computer hanged on the shutting down bit without rebooting for more than half an hour, so I manually shut down the machine and restarted it.
Then a new error message appeared stating “could not find disk”, and I hit the manual fix option, and it now boots to an empty desktop with no launcher and the graphics appears as if this was put on a 640 x 480 resolution, and the screen no longer fits onto my 19" LCD.
I had to use Ctrl-Alt-T to log out and then restart from there.
How can I resolve this issue?
