I can't use startup key combinations
I tried to start up as a single user but the combination cmd-S did not work. As I was mucking around with the issue I realized that that NONE of the startup key combinations work. As if the keyboard were not connected, or something. I do not have a problem with the keyboard during the normal use of the computer.
I disconnected all peripherals, fixed permissions. Any suggestions for cause and solution?
