You got me an insight!

I looked for how block the touchscreen. I found [1] and have blocked it.
The issue got away. But, I do not known if the problem was with the hard
or a software bug. In any case, I do not remember a day that I have been
used the touchscreen. So, in this mean time, it is not necessary.
