While typing some text, the touchpad signalled the mouse some strange moves. Sometimes it marked parts of the text and the next key erased the highlighted text...
First idea was to edit the xorg.conf or something else, but i found a less difficult was via touchpad-indicator.
It can be installed via
apt-get install touchpad-indicatorAlittle problem is, that you can not run it via cli with just calling touchpad-indicator, because ubuntu installs this program into /opt:
/opt/extras.ubuntu.com/touchpad-indicator/bin/touchpad-indicator
Here you can choose "disable touchpad on typing" and you are done...
