Since this is a change in the default behaviour of /sbin/halt and the binary is part of the upstart package, it is not the kernel to blame.
Testcase -> Oneiric, Kubuntu (i.e. KDM used and a KDE desktop), Unity purged: 1. Using KDE's "Shutdown" button actually does a halt with no poweroff, no matter if the "Shutdown" sequence is initiated inside a running KDE session or at the KDM login screen 2. Using the Power button of the PC at the KDM login screen does do the job normally (i.e. does poweroff). 3. Using /sbin/halt inside a KDE session or at the KDM login (in another terminal of course) does only halt no poweroff 4. Using /sbin/halt -p anywhere does poweroff the system as it is expected and as it was in Natty 5. The /etc/init.d/halt script is never executed though it should be at runlevel 0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/809628 Title: "halt" does not power off the system To manage notifications about this bug go to: https://bugs.launchpad.net/upstart/+bug/809628/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
