Title:
syndaemon "-t" option fails, in turn making touchpad disable-while-
typing not work
Status in xserver-xorg-input-synaptics package in Ubuntu:
Confirmed
Bug description:
I'm on Lenovo T450s, but there are reports of others having the same
problem that touchpad disabling, which is no longer an explicit
option, is not working. This leads to data loss and frustration when
typing/editing, etc.
With default settings, I find that syndaemon has been run with the
following options:
$ ps aux|grep synd
meuser 2798 0.0 0.0 22504 2784 ? S Jul15 0:02 syndaemon
-i 1.0 -t -K -R
However, this fails. My palms/ base of my thumbs, in particular, hover
over my touchpad while typing and frequently cause unintended motion
AND mouse-click events, highlighting and deleting text, switching
windows, etc.
The diagnosis seems to be (http://askubuntu.com/questions/299868
/disable-touchpad-while-typing-does-not-work) that the -t option is
not working, ie mouse clicks are still allowed when it is called.
The following two commands are a work-around for me under 16.04 on
this hardware. They result in perfect touchpad disabling while typing:
killall syndaemon
syndaemon -i 1 -KRd
