Public bug reported:
I run Ubuntu 12.04.1 on my Dell Latitude D610 laptop. Sometime within
the last month (Jan 2013) I did a normal update. Now suspend/sleep and
hibernate no longer work. If I close the laptop lid (suspend) the screen
goes blank, but the cpu (and fan) continue to run. When I open the lid,
the screen sometimes comes back and and the laptop continues to run. If
the screen doesn't come back I can usually bring it back with "Super
F7". But obviously no suspend or hibernate is a major problem as it
exhausts the battery and overheats the laptop if I put it in my
backpack. In addition, the cpu mode is now always set to "Performance"
not to "OnDemand" as it used to be (and should be) set. And as I said
above they worked before my January, 2013 update. And it is absolutely
repeatable.
