Bug#653156: xserver-xorg-input-synaptics: description in man-page brakes functionality of the driver

[Jörg-Volker Peetz <jvpeetz@web.de>]

Hi Julien,

with the synaptics version 1.5.99 my old /etc/X11/xorg.conf containing the
"Protocol" "auto-dev" option works.
I downloaded the archive

http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/snapshot/xf86-input-synaptics-0cd5a77c3a455e942929eb4d5412fa51630ed13f.tar.bz2

compiled and installed synaptics_drv.so and restarted the X server.
In /var/log/Xorg.0.log it now reads

[170712.540] (II) LoadModule: "synaptics"
[170712.540] (II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
[170712.540] (II) Module synaptics: vendor="X.Org Foundation"
[170712.540] 	compiled for 1.11.2.902, module version = 1.5.99
[170712.540] 	Module class: X.Org XInput Driver
[170712.540] 	ABI class: X.Org XInput driver, version 13.0

[170712.540] (II) Loading /usr/lib/xorg/modules/input/synaptics_drv.so
[170712.540] (**) ETPS/2 Elantech Touchpad: always reports core events
[170712.540] (**) Option "Protocol" "auto-dev"
[170712.540] (**) Option "Device" "/dev/input/event5"
[170712.540] (--) synaptics: ETPS/2 Elantech Touchpad: x-axis range 32 - 544
etc.

Thanks for your care.

Best regards,
Jörg-Volker.
