suspend happens through logind since Ubuntu 13.10. The package depends on libsystemd-login-dev, and according to the build log (https://launchpadlibrarian.net/188689398/buildlog_ubuntu-vivid-amd64 .cinnamon-session_2.2.2-5build1_UPLOADING.txt.gz) it uses systemd for session tracking. Our systemd package ships all libraries, we didn't disable any.
So I suggest debugging what cinnamon-session tries to call when it determines whether suspend is available, there's obviously some bug there. ** Package changed: systemd (Ubuntu) => cinnamon-session (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1446276 Title: Suspend not available in Cinnamon after upgrade to Ubuntu 15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cinnamon-session/+bug/1446276/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
