just downloaded 12.10 and used the "Startup disk creator" application on my desktop to install ubuntu on a new notebook.
i disable the safeboot shenanigans, boot from the USB, get the first screen where i select the language.
from there, touchpad does not work... ok, I press TAB to highlight the "try ubuntu" button and press Enter.
it takes some seconds to load the Desktop and... rotates the screen 90 degrees to the right!
from there i could press the flag-key, type display, press TAB to disable clockwise rotation, and press tab again to try to guess when it's on the OK button (as it's out of the screen since i only had 768px of heigh --now width) and i'm back to a normal desktop.
dmesg does not say anything useful. I don't even know what i'd say besides this anecdote if i'm to file a bug.
I will try to install and see if that happens with the full image... now off to have some fun with shrinking win8.
