[Bug 324172] Re: Flickering Lines on screen

[Bryce Harrington]

** Description changed:

  I noticed that Ubuntu computers may sometimes start up or resume from
  suspend and show many lines over the screen. Everything is fine except
  there are a bunch of black flickering lines over the screen that look
  like this:
  
                              _                                    _ 
                              _                                    _ 
                              _                                    _ 
                              _                                    _ 
                              _                                    _ 
                              _                                    _ 
                              _                                    _ 
  
  This only happens sometimes, and when it does, a Ctrl-Alt-backspace or suspend and resume usually fixes it.
  This has happened on a hardy computer and also on an intrepid computer.
  I couldn't get a screenshot of this happening, when I screenshot it it looks normal, without these lines.
