I pressed the combination of keys that would produce ScrollLock.
ScrLk is shown in blue on the NumLk physical key, therefore to get
ScrLk I physically pressed Fn+NumLk in order to get the ScrLk key.
When I pressed Fn+NumLk, I got the following output from "keymap -i"

scan code: 0x46 key code: scrolllock

Although the keyboard emits 'scrolllock', the rest of the software
does not interpret it as such, and the Scroll Lock LED is not lit up
(and it's not working).

These are what I get when I press the keys. I did not adjust the
output or try to tinker in /lib/udev/keymaps

Thanks. I can test the fix for the touchpad toggle.

ADDITIONS:
1. I just tested Fn+F7 (that produces "switchvideomode") with HDMI
output and it works fine.
2. I also checked again Fn+F5/Fn+F6 (decrease/increase brightness) and
I verified that they perform a "switchvideomode".
That is, currently, on a dual-head setup, both Fn+F5/Fn+F6 work
exactly like Fn+F7 (switchvideomode), instead of affecting the
brightness.
