If you have intel graphics hardware which locks up or corrupts the screen when closing the lid, it's possible you may need the PipeA quirk. Please see the following link for more info:

ddumanis, if adding 'Option "ForceEnablePipeA" "true"' in your xorg.conf as described in that link solves the issue, please post your lspci -vvnn output and assign this bug to me, and I'll incorporate a quirk for fixing it. Everyone else - if this fixes it for you, please file a new bug as described in the above page.
