[Bug 540134] Re: Screen backlight doesn't come on again after opening the lid

[Chase Douglas]

Just to be clear, the 2.6.32-16 kernel does contain the patch that fixed
the 2.6.32-15 kernel, but it does not appear to be the complete fix
anymore.

** Description changed:

  The backlight of the laptop display doesn't come back on after closing
  and opening the lid on a Dell Latitude E6400.
  
  This was originally reported as bug #488328 and fixed in kernel
  2.6.32-15 (using http://lists.freedesktop.org/archives/intel-
  gfx/2010-February/005902.html), but reappeared in 2.6.32-16 (which has
- the 2.6.33 drm stack in it, which apparently doesn't contain this
- patch).
+ the 2.6.33 drm stack in it).
