How are you shutting down from KDE when this bug occurs? Is it definitely reproducible after hibernate/resume, and definitely not reproducible without hibernating?
Plymouth is just the splash screen on shutdown; it should not prevent the system from powering off. If it does, this is most likely a bug in the frame buffer driver in the kernel. ** Changed in: plymouth (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/908413 Title: Shutdown after hiberante->restore cycle brings plymouth to idel infinetely To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/908413/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
