I'm running xubuntu 12.04 on a 2007 macbook.
I'm using the laptop with external screen, keyboard and mouse. Yesterday after a dist-upgrade and after I unplugged the external keyboard I noticed that the Lapotop's keyboard was mapped to whatever (J = 1 , L = 3 , M = 0 e.t.c.) however I can login and type perfectly in the login screen and as a guest.
Any suggestions on how to get more information and/or troubleshooting are welcome.
