Fedora 27 and Logitech Marble FX

[achojoao]

Recently, I've purchased a pre-owned Logitech Marble FX trackball. I'm enjoying it in my Fedora 27, but I can't make the scroll work. I'm using an active PS/2 to USB converter in order to connect the trackball to the computer (https://www.amazon.es/dp/B00DHD6TQ6/...740151_TE_item).

The converter is automatically detected and I can use the trackball (except the red button) without problems right out of the box.

lsusb displays this:

It is detected as a a BarCode Reader! (https://usb-ids.gowdy.us/read/UD/13ba)

It doesn't matter. Using xev i can see the events of the three buttons and the ball (again, red button doesn't appear to work).

The output of xinput is:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ xwayland-pointer:13                     	id=6	[slave  pointer  (2)]
⎜   ↳ xwayland-relative-pointer:13            	id=7	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ xwayland-keyboard:13                    	id=8	[slave  keyboard (3)]

I can, for example, use the next command and the middle button doesn't work:

xinput set-button-map 6 1 0 3

Listing the props I get:

	Device Enabled (117):	1

Listing the /dev/input/by-id/ I get:

I have used the command Xorg :1 -configure in order to obtain my xorg.conf file, which is:

...
Section "InputDevice"
  Identifier  "Mouse0"
  Driver      "mouse"
  Option      "Protocol" "auto"
  Option      "Device" "/dev/input/mice"
  Option      "ZAxisMapping" "4 5 6 7"
EndSection
...

Then, I've copied this file to /etc/X11/xorg.conf and made some changes, for example, adding the option of mapping buttons in order to deactivate the middle button, but after rebooting the computer, the middle button still works.

...
Section "InputDevice"
  Identifier  "Mouse0"
  Driver      "mouse"
  Option      "Protocol" "auto"
  Option      "Device" "/dev/input/mice"
  Option      "ZAxisMapping" "4 5 6 7"
  Option      "ButtonMapping" "1 0 3 4 5 6 7 8 9"
EndSection
...

My first objective is to use the middle button as the EmulateWheelButton in order to trigger the scroll. It would be awesome if somebody knows how to "force" the detection of that red button, to use it instead of the middle button.

I've followed several procedures (pretty outdatted):

https://forums.fedoraforum.org/showt...heel-Emulation

And also other steps for the Logitech Marble (not FX):

https://wiki.archlinux.org/index.php...h_Marble_Mouse
https://forums.fedoraforum.org/showt...h-Marble-Mouse

And some mixes, but without success.

Any tip or help will be appreciated! I really need the scroll! Thanks!

Try either or both of these:


sudo nano /usr/share/X11/xorg.conf.d/10-libinput.conf

and add:

Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Driver "libinput"
Option "ScrollMethod" "button"
Option "ScrollButton" "8"
Option "MiddleEmulation" "on"
EndSection

If that doesn't work, then try this:

sudo nano /usr/share/X11/xorg.conf.d/10-evdev.conf

Add:

Section "InputClass"
Identifier "Marble Mouse"
MatchProduct "Logitech USB Trackball"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "8"
Option "XAxisMapping" "6 7"
Option "Emulate3Buttons" "true"
EndSection

In either case, change 8 to 9 if you want to use the right button to activate scroll on this line: Option "EmulateWheelButton" "8" or Option "ScrollButton" "8"

I've tried your configurations, but they don't seem to work for me. Thanks anyway!

Ok, for newbiews like me, Fedora uses Wayland by default. I've changed to use Xorg by default by modifying /etc/gdm/custom.conf and uncomment WaylandEnalbe=false and changes in /etc/X11/xorg.conf started to work.
