Workaround: I found that installing unsupported package 'hibernate' gives laptop-mode-tools the file it required /usr/sbin/hibernate
however I wonder why it doesn't use the the gnome way to hibernate the laptop (as I could make use of suspend / hibernate without an issue before installing hibernate package) and requires such an external unsupported package, this package is also not listed as a dependency or suggeste. -- laptop_mode cannot find /usr/sbin/hibernate thus cannot hibernate laptop https://bugs.launchpad.net/bugs/149324 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
