I have had many (fixable)issues with thinkpads and buttons, but not on x220 specifically. First, it is advised specifically for the x220 to update to a recent bios, http://www.thinkwiki.org/wiki/How_to_make_ACPI_work ... and then install a package called tpb (ThinkPadButtons), I checked and it is still in stable(jessie) here is some more good stuff on the thinkpad x220... http://www.thinkwiki.org/wiki/Category:X220
