I have a fresh Ubuntu 12.04.3 LTS installation and at first everything
worked fine. 2 days and approximately 10-15 reboots after the initial
installation I started experiencing this "blank screen, blinking cursor
in upper left corner" problem with increasing density. After another 2-3
days and a numer of reboots I could only get this blank screen.
I followed the fix / workaround suggested in comment #95 and so far I
have not experienced the problem once, i.e. no problems in rouhly a week
and another 15-20 reboots.
For those working with the issue, below is a list of my HW.
