I had this problem too, however I realised (after browsing /var/log/pm- suspend.log) that I had a custom file to get around a problem in 11.10 -- i.e. I had /usr/lib/pb-utils/sleep.d/00Custom
Removing this solved the problem for me. Not sure if this helps the users above or not, but I thought it worth passing on. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991492 Title: Precise Pangolin Fails to Suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpid/+bug/991492/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
