Bug#781627: synaptics docs

[Matt Taggart <taggart@debian.org>]

Package: xorg
Version: 20150331
Severity: wishlist

I recently did a jessie install on a new laptop, an ASUS UX305FA, and
the install was nearly perfect, everything just worked, yay!

This laptop has a touchpad and I had some minor issues figuring it out
and I have some small suggestions for the documentation at

  http://pkg-xorg.alioth.debian.org/howto/configure-input.html

(and maybe the wiki page at https://wiki.debian.org/SynapticsTouchpad)

1) I couldn't emulate a middle button click by clicking left+right.
Eventually I read in the synaptics(4) man page that,

  "ClickPads do not support middle mouse  button  emulation."

It might be good to mention that and alternatives, maybe something like

  "Touchpads with a button integrated in the touchpad surface (called
  'ClickPad') do not support emulating a middle button click by
  clicking the left and right buttons at the same time. On these
  devices alternatives are using '3 finger click' or setting up a
  dedicated area of the touchpad for middle button using the
  'SoftButtonAreas' option."

2) After typing there is a delay before the touchpad becomes active.
I learned this is controlled by the syndaemon program, which was
already running as

  'syndaemon -i 2.0 -K -R'

with a 2 second delay. But I can't find where those settings are
configured or how syndaemon is even launched. ppid is 1 so init must
be launching it but I can't find anything in /etc/init.d/, /etc/X11,
/etc/default. Compounding the problem is that if you touch the pad
before the 2.0s is up, the pointer won't respond until you lift your
finger and set it back down. 2.0s was too much for me, I have it turned
down to 0.1. So A) document how to adjust it and B) consider turning it
down.

3) The bottom of the configure-input page says:

  "Warning: it becomes quite difficult to use things like Ctrl+click
  in a browser, or Alt+drag to move windows."

I think this is what the syndaemon -K flag is for? (which is on by
default). So maybe the example could be adjusted and that line removed?


Thanks,
