I'm using a macbook pro and I recently upgraded to the 11.10 beta. Suspend no longer works. When I close the laptop lid, I can tell the screen turns off momentarily, but then comes back on. When I open the lid, it's at the unlock screen. The same things happens if I select suspend from the power menu.
What can I do to troubleshoot or fix this? I realize that I'm using beta software, but I'm not sure where to get started working on something like this.
