On 12.10 no blank screen appear IF you do not install fglrx or fglrx-
updates throught ubuntu gui, but instead pop up terminal and do:
sudo apt-get install linux-source linux-headers-generic fglrx-updates
I believe the need for linux-source and linux-headers-generic is whole
new bug, different from this one.

Title:
Ubuntu fglrx cannot recognize video memory at boot, blank
screen[workaround]
Status in “fglrx-installer” package in Ubuntu:
Fix Released
Bug description:
Using a regular 2011 imac 21,5" with AMD radeon hd 6770m and ubuntu
12.04 mac specific 64bits; installing the 'additional drivers' non
post update fglrx, be it with an updated system or not, results in a
black screen at the next ubuntu login screen; ubuntu recovery
failsafex cannot initiate ubuntu anymore saying ''no suitable screen
were found'; only by just loadind ubuntu recovery and type reboot at
recovery command line mode can I acess ubuntu partition once only,
before having to repeat the process. In rare cases one must also type
'aticonfig --initial' to login once at ubuntu before it returning to
the black screen state at the next boot.
The only way to get out of the blackscreen for the procedures above is
by rebooting the mac using its powerbutton.
fglrx 'post-update' do not even install, being the system updated or
not. AMD site radeon driver from the site does not work if an ubuntu
specific package is generated(it also seems this is the package used
by ubuntu); only the plain non ubuntu AMD driver install to Xorg truly
works(no more black screens), the distorted ubuntu initial logo before
login shows the driver was truly recognized(nvidia also distorts the
logo when recognized), also the solution mentioned only works if you
have a clean install of ubuntu(the home folder does not matter, no
clean install of /home is needed)
The ati driver package at ubuntu repository from software center seems
to be the regular fglrx non post update, so, same results.
The Ubuntu Open source driver works, but is slower even to get a login
screen, also it is useless for true 3d graphics(like games) for my
video card model(AMD radeon hd 6770m).
For drivers which were 'tested by ubuntu developers' me and countless
others expected more.
I cannot test this right now, as to test this I should wreck my ubuntu
desktop again; and my internet connection isn't restored yet(very low speeds);
and the testing is a bit dangerous to my hardware I guess, as I got a very soft
'stain' at my screen, exactly where the ubuntu unity left dock use to
stay(perfectly at the dock right limits) which persists though mac boot and my
OS X system and which only appeared after the several video driver attempts
above.
