I'm running Slackware on a Sony Vaio ultrabook and after the installation I had to add
append=" vt.default_utf8=0 kbd-reset"
in lilo.conf in order to have the keyboard working.
It was working perfectly until some days ago when for some reason I have lost access to most of the key from boot stage. I can't even type "single".
The result is I can't login since just few key actually work.
I've just found however that hitting the Fn key allow me to get fully access to the keyboard.
The point is what is the cause of this and how to fix it.
Did someone have a similar experience?
