Screen blanks on lid close, never comes back

Mon Jan 17 21:32:24 UTC 2011

The issue is not with suspending but with screen blanking.

Power Manager (AC and Battery) do not offer the option to do nothing on lid
close ("When lid is closed"), but I tried it by setting it in gconf.

As far as suspend goes, I was simply saying that I observe the same issue if
I close and reopen the lid quickly. If I let the laptop suspend and resume,
the screen comes back correctly. But I don't want my laptop to suspend when
the lid is closed.
