don't know if this is really useful, but it shows that the problem is not OS dependent. http://www.insanelymac.com/forum/index.php?showtopic=192864
What I read there is that there is an issue about the nvidia card driver and the kernel. So maybe if you just use a generic driver, it could solve your shutdown - poweroff problem, but you won#T use the nvidia driver, what could be but maybe is not an issue... But it is just another guess! ...yes of course also other users have an similiar but maybe a slightly different problem...and as we said before: it worked with 10.04 so it will with 12.04! -- 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
