I have a Logitech Marble Mouse Trackball, with its scrolling ability configured as follows:
#!/bin/bash dev="Logitech USB Trackball" we="Evdev Wheel Emulation" xinput set-int-prop "$dev" "$we Button" 8 8 xinput set-int-prop "$dev" "$we" 8 1
This allows me to hold down the small left-button and scroll by rolling the trackball up and down, with side-to-side motions having no effect.
This is a clean install of Xubuntu 12.04 LTS running Xfce.
Using Kubuntu (and many other desktop environments), I was able to:
- Select text with the mouse (either by dragging the selection or double-/triple-clicking words).
- Middle-click (emulated as the small right-button) to paste in another window (or the same window).
I have tried to re-enable the behaviour using:
- marble mouse middle click fail in 12.04
gsettings set org.gnome.settings-daemon.peripherals.mouse middle-button-enabled true returns
No such schema 'org.gnome.settings-daemon.peripherals.mouse'.
dconf-editor tool does not show
org::gnome::settings-daemon::peripherals::mouse. The closest I could find is
org.gnome.desktop.a11y.mouse, but it does not have a setting for
How do I enable "middle-click" for the trackball so that the small right-button performs a paste of the copy buffer?
