[Bug 992584] Re: Lightdm displays running in low resolution box upon booting

I'm running 12.04 and cannot use lightdm because of this issue.  I
always get the low resolution mode message and often can't get beyond it
because the keyboard/mouse appear to be locked.  I use gdm as a
workaround.

Title:
  Lightdm displays running in low resolution box upon booting

Status in “upstart” package in Ubuntu:
  Confirmed

Bug description:
  Upon booting or rebooting the lightdm greeter displays a box that says
  the screen is running in low resolution mode and offers to allow you
  to reconfigure graphics.

  if you CTRL-ALT-F1 and login then "sudo killall xinit" followed by
  "service lightdm start" the normal login screen is then displayed.

  The low resolution issue does not always happen as most of the time it
  goes to the normal login box, but it has periods where is happens
  frequently / all the time.

  Looks like a timing issue when booting (possibly) We are running 64GB
  SSD's so booting is quite rapid.

  12.04 Ubuntu AMD64
  Intel i5 2400 4GB ram
