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.

do you have enough swap in relationship with ram on your computer? Or it might be that some device is failing to suspend. Try to run:

 echo 1 > /sys/power/pm_trace

as root then after the failed suspend run dmesg "hash matches" you the last device on the list is probably the one failing to suspend for you.
