Looks like both problems were related to the fact that I used update- manager for 3 years to update between versions.
I made fresh 8.10 install and sleep/wake-up works fine for me now. Regarding sound button problems I've reported bug #290636 which has also been solved by the fresh install and config changes in gnome. -- Wakeup after suspend to RAM not working https://bugs.launchpad.net/bugs/106198 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
