Fedora 26 Touchpad enable toggle key does not work

edit

Hi, I have freshly installed Fedora 26 to a Lenovo Yoga 900 and I cannot get the touchpad enable/disable toggle key to work. I had the enable/disable toggle key working in Fedora 25. My process has been:

dmesg

[ 4086.176227] atkbd serio0: Unknown key pressed (translated set 2, code 0xbe on isa0060/serio0).
[ 4086.176237] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.

xmodmap -pke

keycode 200 = XF86TouchpadOn NoSymbol XF86TouchpadOn
keycode 201 = XF86TouchpadOff NoSymbol XF86TouchpadOff

sudo setkeycodes e03e 191 # I read somewhere to subract 8 from xmodmap, it worked in Fed. 25. I tried 199 as well and it didn't work either.

$ sudo showkey -k

kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode  28 release
keycode 191 press      # this is when i pressed the toggle touchpad key
keycode 191 release    # this is also when i pressed the toggle touchpad key (before release)
keycode  29 press
^Ccaught signal 2, cleaning up...

$ sudo showkey -s

kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
0x9c 
0x74 0xf4             # this is when i pressed the toggle touchpad key

I am aware that the Synaptics driver has been retired for F26 (https://fedoraproject.org/wiki/Changes/RetireSynapticsDriver) and I suspect that installing the Synaptics driver may solve my issue. I would prefer not to install the Synaptics driver if it is not recommended, and it seems it is not the future.

Thank you for reading my question. Any and all help will be greatly appreciated.
