Andre Salvatierra, thank you for taking the time to report this bug and
trying to help make Ubuntu better. However, Elementary OS is not a
software package provided by the official Ubuntu repositories. Because
of this the Ubuntu project can not support or fix your particular bug.
Please report this bug to the provider of the software package. Thanks!

Title:
  Black screen on startup - nothing is visible (intel) unless nomodeset

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  Running on an Acer Aspire 4786.
  Intel Core 2 Duo P7350 2GHz
  2GB RAM
  Intel Corp. Mobile 4 Series Chipset Integrated Graphics Controller
  (No Proprietary Drivers in use)

  The screen goes completely black when booting from the liveUSB,
  whether the option is to "Install elementary OS" or "try... without
  installing".

  This has happened to me before while using the Gnome Shell Remix of
  Ubuntu 12.04. The first few months of using 12.04 were fine; the
  problem appeared after an update (I can't remember the time period,
  specifically). At first I could use the desktop environment fine
  without any problems. As time went by, the screen would just go black
  for no apparent reason. It got worse as time went by, and pretty soon
  after every boot up the screen would black out.

  I bring it up because maybe (I think) it's relevant to this problem.
  ('Course, could be a problem just on my end, in which case, that would
  suck even more).

  The thing is - despite the black screen - the computer responds to input: for example, pressing super + some F(n) keys would occasionally cause the screen to flicker / display the login screen as one would see it normally for a split-second, showing the username / password fields. You can move the cursor, click around, and the system will respond - you just can't see anything.
