Comment 25 for bug 1351772

@Christopher,

On Thinkpad T450s, there is only one trackpad device in xinput, and it's a PS/2 device.
So, Thinkpad T450s does not need this workaround solution.
The workaround solution is to block the PS/2 trackpad device.
That's why the workaround solution make your trackpad lost function.
I think I need add more condition in the workaround package.

I borrowed a thinkpad X250, the xinput is similar with yours beside the Wacom Bamboo 2FG and the touchscreen.
When I am typing, the 'tap to click' is disabled. So, I won't be interrupt by palm when I typing.
For your case, I have no idea what causes the "disable tap while typing" function fail.

Another thing, the "disable touchpad while typing" option is removed.
Currently, the actual behavior is "disable 'tap to click' while typing".
I think this behavior make sense,
i.e. Some gamers will use both the keyboard and the touchpad at the same time.
