The installation (upgrade) of Linux Mint 12 on my EEEPC left the system with some little problem to be solved together with many applications that had to be reinstalled. Not all of these problems are Mint-specific since one, at least, hat its solution reported on a Ubuntu forum. And I'm not also sure if these problems appears after upgrading from Ubuntu to Mint 12 or after a fresh installation too. By the way all have been solved with a couple of shell commands. I spent more time looking for solutions than executing them, so I hope it might be useful to have them all in the same page.

sudo os-probersudo update-grub
