Logitech K780 Keyboard replaces function keys(F1-F12) with [hot keys + media keys] by default.
For those who are accustomed to use function keys, it may be a huge inconvenience.
Logitech currently(Aug 2019) does not support any offcial linux application(and perhaps they are not willing to!).
This is to invert from [Hot keys + Media keys] to function keys(F4-F12) whenever you start up your computer.
- This shell script was tested in Ubuntu (18.04) only
- May work in other linux versions if they have xmodmap
- Function keys inverted are only [F4 to F12] (F1, F2, F3 have not been inverted)
- Download K780_invert_ubuntu.sh
- Launch [Startup Applications] in ubuntu
- Browse your computer and select [K780_invert_ubuntu.sh] and save it.
All Done!
