I've had this problem with 12.04 for a while. Had no idea what caused it. Found a fix in ubuntuforums renaming priorities in upstart scripts but never bookmarked the thread(12.04beta)
Struggled on recent install until I noticed reboot/shutdown worked when dropping to tty1 and stopping lightdm service. I have updated my AMD graphics driver to Catalyst version 12.4 and so far everything is back to normal, including plymouth. Will see if it persist. -- Radeon HD 6700 Series ; i7-2600 ; H67 Express Chipset Linux bean-desktop 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Desktop Packages, 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 Status in The Session Menu: Incomplete Status in “gnome-session” package in Ubuntu: Invalid Status in “indicator-session” package in Ubuntu: Invalid Status in “linux” package in Ubuntu: Confirmed Status in “upstart” package in Ubuntu: Invalid Status in “gnome-session” source package in Precise: Invalid Status in “indicator-session” source package in Precise: Invalid Status in “linux” source package in Precise: Confirmed Status in “upstart” source package in Precise: Invalid Bug description: Shutting down the computer using the menue does not work always correct.
