dexconf thinks Synaptics driver is called 'synaptic'

[Gordon Ingram]

While an entry is made in /etc/X11/XF86Config-4 for the synaptics touchpad, it
simply points it at /dev/psaux and treats it like a common PS/2 mouse.

To get it working properly I had to:
Add 'Load "synaptics"' to the module section of XF86Config-4
In the InputDevice section for the touchpad, change 'Option "Device"
"/dev/psaux"' to 'Option "Device" "/dev/input/ts0"' (I'm not entirely sure
whether the touchpad would reliably happen to be this device on other setups,
but I kind of think it will be)
In the InputDevice section for the touchpad, also add some stuff from
/usr/share/doc/xfree86-driver-synaptics/README.Debian:

Section "InputDevice"
        Identifier "Synaptics Touchpad"
        Driver "synaptics"
        Option "SendCoreEvents" "true"
        Option "Device" "/dev/input/ts0"
        Option "Protocol" "auto-dev"
        Option "LeftEdge" "1700"
        Option "RightEdge" "5300"
        Option "TopEdge" "1700"
        Option "BottomEdge" "4200"
        Option "FingerLow" "25"
        Option "FingerHigh" "30"
        Option "MaxTapTime" "180"
        Option "MaxTapMove" "220"
        Option "VertScrollDelta" "100"
        Option "MinSpeed" "0.06"
        Option "MaxSpeed" "0.12"
        Option "AccelFactor" "0.0010"
        # Option "SHMConfig" "on"
        # Option "Repeater" "/dev/ps2mouse"
EndSection

I'm fairly sure this could be done automatically. Couldn't it?

It should be -- I assume you have a laptop? When you run 'laptop-detect; echo
$?' as root, what gets printed? I suspect the problem is that we can't detect
your specific laptop as a laptop.

It's a Fujitsu-Siemens Amilo D 1840, though the same laptop is branded by
several companies. Running 'sudo laptop-detect; echo $?' gives:

We're a laptop

Same here. The problem is in dexconf which writes "synaptic" where it should
write "synaptics" (line 388 in version 4.3.0.dfsg.1-6ubuntu18).

I had the same problem.
Changing "synaptic" (that useful package managing tool) by "synaptics" makes it
work, including extra scrolling functionalities.

Fabio, can we please do this as part of ubuntu19?

[Daniel Stone (daniels)]

I've incorporated this patch into the 4.3.0.dfsg.1-6ubuntu20 packages I've
prepared, and this will all get rolled into an upload reasonably soon: thanks
for the report.

[Daniel Stone (daniels)]

Fixed in 4.3.0.dfsg.1-6ubuntu20.
