[Nix-dev] synaptics touchpad configuration question

Thanks for the helpful tips. synctl could change the relevant variable but
to no effect; the X log seems to indicate why (see the line (EE) synaptics:
ETPS/2 Elantech Touchpad: Synaptics driver unable to detect protocol). My
first reference at the end seems to indicate it may be a driver issue, that
I've so far been unable to resolve by playing with the xserver config, but
maybe I am missing something.

Updated config:

enable = true;
layout = "us";
videoDrivers = [ "nvidia" ];
config = ''
Section "ServerLayout"
Identifier "Layout0"
InputDevice "ETPS/2 Elantech Touchpad" "CorePointer"
# Reference the Screen sections for each driver. This will
# cause the X server to try each in turn.
Screen "Screen-nvidia[0]"
EndSection
Section "InputDevice"
Identifier "ETPS/2 Elantech Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/input/event10"
#Option "Protocol" "auto" # Causes problems in recent X
EndSection
'';
synaptics = {
enable = true;
additionalOptions =
''
Option "RBCornerButton" "3"
'';
};
desktopManager.xfce.enable = true;
};
The config still results in the same protocol issue. Starting to look like
I may take this upstream...?
