I have the same problem on 6 notebooks in my recent installation of ubuntu 12.04 desktop (either amd64 or i386).
Three are mine: Toshiba L640 (i3 box with amd/ati video chip, amd64) acer aoa150 (netbook) acer aod150 (netbook too) Three are on my 3 students: asus (netbook) asus UX31E (i5, new slim notebook, amd64) acer MS2346 (i5, new slim notebook, amd64) Because we seldom (it does succeed sometimes) succeed to shutdown from system menu, now we all rely on <alt-f2> sudo poweroff, which is sure to turn off it. p.s. If it fails to finish, it will stay at a high level of power consumption, e.g. My toshiba L640, it will go from 22W to 35W Asus UX31E, it will go from 17W to 29W. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/987220 Title: System does not power off reliably when "Shut Down" chosen from GUI To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-session/+bug/987220/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
