I am using Ubuntu 12.04, in a laptop that I carry around and use with different physical keyboards (as I don't feel comfortable with laptop keyboards)For one of those keyboards (Dell SK-8135) the Super and Menu (?) keys are not recognized:xev ignores keypresses completely for those 2 keysshowkey -s (ran as root, in the console) also ignores keypresses completelyI know that these keys in my keyboard work on other computers (I could not try them in another Linux based computer).  I am 80% sure this particular keyboard used to work ok with an older version of Linux I used to have (it could have been a similar keyboard).I tried also, with no avail, things of the like setxkbmap  -model dellsk8135setxkbmap  -model dellsk8135 -print | xkbcomp - $DISPLAYAny debugging clues appreciated; I am not sure how to go below showkey command.
Keyboard key is not recognized even with showkey
