So I am running Linux Mint 14, Cinnamon, from a USB, with persistence, with the help of Universal-USB-Installer, and when I click on the shutdown button Linux logs out but nothing shuts down. I am able to shutdown via the terminal using
"sudo shutdown -h now" OR "sudo shutdown -P now"
but this is not really an ideal solution
I stumbeled across a solution involving modifying the grub file http://forums.linuxmint.com/viewtopic.php?f=42&t=117686&p=651173&hilit=shutdown#p651173 but I don't think it's the same issue and the solution does not work and returns this error when I try to update-grub "/usr/sbin/grub-probe: error: failed to get canonical path of /cow."
I think this could be a problem with the fact that I'm running Linux off a USB, but I'm disappointed something as basic as shutdown would not work. I'm new to Linux and I'm not even close to actually installing Linux on my laptop yet.
If there is anyone that can provide a solution or point me in the right direction, it would be appreciated
