Title:
  vertical coloured lines / herringbone pattern on startup

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  This problem occurs intermittently on my Dell Inspiron 1501 laptop.
  For instance, on booting the Saucy beta 2 release from USB stick; or
  today, booting the installed 13.10 beta 2 with all updates current.
  But not always.

  The workaround is to wait for the screen to blank on power save; when
  it is reactivated, the display is fine.  Or if screen blanking is not
  engaged, close the lid, wait, and open it again.

  The screen is 100% illegible when this happens.

  This problem has been noted by myself and others and was formerly
  tracked as bug 572521 but the originator of that bug no longer has the
  hardware.

  This is my testing machine so I am able and willing to try anything on
  it.
