Just mouse, nothing specific.
Can't remeber installing such package, but I don't think my touchpad
must be configured by DE. I strongly believe this should be done via
/etc/X11/xorg.conf.d/ and therefore left DE-independent. My one and
only pain is that I can't configure per-window or per-application
keymap settings via Xorg.

Hah, I see. I use archlinux which, as a matter of fact, doesn't
configure synaptics driver or indeed Xorg by default.

Anyway, thank you for your time!
