I experienced similiar problems when notebooks (their CPU) are getting hot: - the machines stuck / freezes and i wasn't able to do anything.
Machines got hot when the power management didn't work as expected...and the problem was the ACPI or APM configuration/manipulation in BIOS (if there was any possibility at all) or in the kernel...and things got better and started to work with ubuntu 8.04 The great problem is, so do i think, that there are many hardware vendors, and they all have different components from different manufacturers and they all have different BIOS Software and not all have the time to stick to conventions/norms/standards or they don't like the standards....but it is really hard to find out, if it is a real hardware damage or a workaround, with which one could live... In your case there must be a solution, because it worked with 10.04 LTS, so it has to work with 12.04 LTS too. Maybe there was a certain/extra kernel module in10.04 in use for your notebook, which made it work as expected? -- 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.
