[beagleboard] Re: Touch on LCD Chipsee (BBB-EXP-C) stopped respond

[Radovan Chovan]

The same problem appears with touchpad or even with mouse.
Discussion here: 
https://askubuntu.com/questions/528293/is-there-a-way-to-restart-the-touchpad-driver


Using these commands
xinput disable EP0790M09
xinput enable EP0790M09

input driver for "touch" functionality restarted and then touchscreen 
started respond again.

But, it will be useful, if there is solution with preventing of this touch 
problem.

Thanks for your answer, but what about *capacitive Chipsee *touchscreen 
behaviour?
I think the whole problem is related with multitouch, but I don't know how 
correctly set some touchscreen options in OS Debian.

It's possible that your palm deposits water or body oils and confuses the
resistive sensors. Can you try wiping the display with a paper
towel,perhaps sligtly moist with alcohol?

So, now I have figured I can reproduce same problem with rezistive display 
from 4D Systems (BBB revC and Debian Wheezy(not Jessie)), when I touch 
display with my palm.

But command
sudo /etc/init.d/lightdm restart

doesn't help at all. Display reboot with java application autostart lasted 
20 seconds, but touch didn't still respond. When I touched this resistive 
display, I cannot still accomplish to start touch again after many tries 
with palm and finger touches.
