Possible to flip scroll direction of mouse only?

unbrand

I've been running NetBSD 10-Beta on my T440P for a few days now, and generally things look good. One thing that I'm hitting a wall on is this: out of the box, 2 finger scroll works great in X! When I plug in my Logitech external mouse, the scroll wheel moves opposite to the trackpad. So, I'd like to be able to flip the mouse scroll wheel to match the behaviour of the trackpad.

When I try
sudo wsconsctl -m -w scroll.reverse=1
that reverses the trackpad.

Every xorg.conf thing I've tried flips both mouse and trackpad at the same time.

I can't seem to flip just the external mouse scroll wheel.

In dmesg, the mouse is identified as "uhidev0" but in the Xorg logs, there's no mention of a mouse1 or Logitech anything.

Is what I want to do just not realistic given the current state of things? If so, ok. But if there's something I'm missing, I'd sure love to know what it is.

Any tips? Thank you!

I just looked at the code, and it looks like that setting only works if you have a Synaptics touchpad. Setting it on anything else is useless, so I'll just ~~strike out~~ this first section:

~~Try setting that property only on the USB-mouse. First, find the USB-mouse. Use either:~~

$ fgrep wsmouse /var/run/dmesg.boot
wsmouse0 at pms0 mux 0
wsmouse1 at ums0 mux 0
$

~~(pms0 is the PS/2 touchpad and the USB-mouse is ums0.)~~

~~or, use wsconsctl:~~

$ sudo wsconsctl -f /dev/wsmouse0 -ma
type=ps2
scroll.reverse=0
scroll.distance.x=12
scroll.distance.y=12
repeat.buttons=none
repeat.delay.first=0
repeat.delay.decrement=0
repeat.delay.minimum=0
$

~~That's the touchpad.~~

$ sudo wsconsctl -f /dev/wsmouse1 -ma
type=usb
scroll.reverse=0
scroll.distance.x=12
scroll.distance.y=12
repeat.buttons=none
repeat.delay.first=0
repeat.delay.decrement=0
repeat.delay.minimum=0
$

~~This one looks like the USB-mouse. Change:~~

$ sudo wsconsctl -f /dev/wsmouse1 -m -w scroll.reverse=1

If doing this doesn't work--and it didn't for me (see update above)--then you can fix it in X. Create a ws.conf file like this:

$ cat /etc/X11/xorg.conf.d/ws.conf
# Force creation of 2 separate input devices on NetBSD
#
Section "ServerLayout"
    Identifier  "X.org Configured"
    InputDevice "Mouse0" "CorePointer"
    InputDevice "Mouse1" "CorePointer"
EndSection

# Don't add the default `/dev/wsmouse` device. On NetBSD, this
# device is added _after_  our `Mouse0' and `Mouse1' devices,
# and so any customizations to those get overridden :(.
#
# (Note: hotplugging may not work with this setting.)
#
Section "ServerFlags"
    Option	"AutoAddDevices" "off"
EndSection

# This is the PS/2 touchpad; use standard mapping.
#
# (Use: fgrep wsmouse /var/run/dmesg.boot
# or wsconsctl(8) to find out which is which.)
#
Section "InputDevice"
    Identifier  "Mouse0"
    Driver      "ws"
    Option      "Device" "/dev/wsmouse0"
    Option      "ZAxisMapping" "4 5"
    Option      "WAxisMapping" "6 7"
EndSection

# This is the USB mouse; swap Z-axis buttons.
#
Section "InputDevice"
    Identifier  "Mouse1"
    Driver      "ws"
    Option      "Device" "/dev/wsmouse1"
    Option      "ZAxisMapping" "5 4"
    Option      "WAxisMapping" "6 7"
EndSection
$

If you want to change back to the standard mapping without restarting X, use xinput:

$ xinput --list		# find input devices
$ xinput --set-button-map Mouse1 1 2 3   4 5   6 7

To swap it again:

$ xinput --set-button-map Mouse1 1 2 3   5 4   6 7

Here's my xorg.conf:

Section "InputDevice"
        Identifier  "Mouse1"
        Driver      "mouse"
        Option      "Protocol" "wsmouse"
        Option      "Device" "/dev/wsmouse1"
        Option      "ZAxisMapping" "5 4 6 7"
EndSection

Hmm, dunno why those inner lines aren't indented when I post, but they are indented my file. I'm not an animal. 🙂

This xorg.conf is at /etc/X11 and seems to have no effect at all. If I delete this file, there's no change in behaviour. Other things I've tried (can't remember exactly) in this xorg.conf would reverse the scrolling for both. I think that was when I specified "/dev/wsmouse" .

Any ideas?

unbrand try out @rvp ' s suggestion from this discussion:

Fixed it for you, just use three backticks instead of one 😉

Thanks for the tip, Jay. I should have mentioned that I have already been through that thread you linked, reading it carefully and trying things. Lots of good info in that thread, but nothing directly related that I could tell. Generally, though, those tips were how I ended up with the xorg.conf posted above.

The suggestion you linked to is for something else, I believe. I'm looking to reverse the mouse scroll button while leaving the touchpad behaviour intact.

If I am missing something pls let me know!

pin Awesome, thanks!

rvp Magic! Your "changing it in X" worked a treat. I followed your suggestions and saw the same behaviour you did, like how wsconsctl couldn't make this wheel scroll change stick.

I was really close earlier today! I missed the "ws" as the driver in combo with the 2 device-listing in the mouse.conf and the bit in there about /dev/wsmouse. Ok, maybe not that close after all 🙂

All is well. Thanks so much rvp! Very happy to get to a good place. Much appreciated!
