Public bug reported:

Since dist-upgrading to Ubuntu 11.04 my Lenovo U160 does not fully come
back from stand-by or hibernation.

The display remains black although the back-light is on, similar to bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/608907/
The same issue arises when you leave the machine alone for a while: it first starts the screensaver but after a while it will also go into more power-saving routines. So if you leave it alone for 20 minutes or so, the problem is the same as when you manually switch it to stand-by or hibernation.
