[Nix-dev] synaptics touchpad configuration question

[Kirill Elagin]

Well, the next thing to check is the X log. When X detects an input device,
it lists all the options it is going to apply, so check that RBCornerButton
is actually applied.
Also, does the option work if you set it manually (I mean, not in X config,
but by actually calling `synclient` from the terminal)?

P.S. As a side note I’d like to mention that `synclient` is an old tool (it
basically just emulates the old interface on top of the new one for
compatibility). XInput2 is the new interface and the command is `xinput`
(check `man synaptics` for the mapping between xinput properties and X
server config options). Not that it is important in this particular case,
but it is just good to know that there are some things you can’t do in
synclient.
