Conflicts with Other Tools

Running LinguaX alongside other mouse utilities or input automation tools can cause conflicting behavior. Because several tools can all intercept the same low-level mouse and keyboard events, only one should own each responsibility.

Mouse tool conflicts

Tools like Logi Options+, Mos, LinearMouse, BetterMouse, and Mac Mouse Fix also hook into scrolling, button mapping, and pointer behavior. Running them at the same time as LinguaX can produce:

• scrolling that double-smooths, stutters, or feels inverted
• side-button or gesture actions firing twice, or one tool overriding the other
• pointer speed that fights between two tools
• a button that works in one app but not another, because another tool claims it first

Isolation test (mouse)

1. Quit other mouse utilities (including ones running only in the menu bar or as login items).
2. Keep only LinguaX running.
3. Test smooth scrolling, one side-button mapping, and one gesture.

If behavior stabilizes, a mouse-tool conflict is likely.

Mitigation (mouse)

• Choose one tool as the source of truth for each responsibility:
  • smooth scrolling owned by one tool only
  • button/gesture mapping owned by one tool only
  • pointer speed owned by one tool only
• In the other tool, disable the overlapping feature rather than the whole app, if you still need its other features.
• Avoid mapping the same button to actions in two tools at once.

Resolve mouse-utility conflicts on macOS (Options+, Mac Mouse Fix, …)

When two mouse utilities intercept the same events, only one can own each event stream. Two ways to enforce that, in order of reversibility:

Option A — Revoke Input Monitoring from the other tool (reversible)

Fastest fix, undo in one click if you change your mind.

1. Open System Settings → Privacy & Security → Input Monitoring (repeat for Accessibility).

   

2. Turn OFF the toggle next to the other tool. Keep LinguaX ON.

   

3. Verify: LinguaX → Diagnostics Center → Realtime Events → press the side button → the event should flow in.

Trade-off: hardware-level settings the other tool wrote to the device (Options+ SmartShift, DPI, backlight) persist even after Input Monitoring is revoked — those aren't tied to system permissions. LinguaX has its own pointer-speed and DPI controls that cover the same ground natively — see MX Master 3S setup without Logi Options+.

Option B — Uninstall the other tool (clean slate)

If you don't rely on any of the other tool's remaining features, uninstall is the cleanest fix — nothing to flip back on the next macOS update.

• Logi Options+: use the app's built-in uninstaller, then remove any leftover LaunchAgents at ~/Library/LaunchAgents/com.logi.optionsplus.*. Full step-by-step in the migration guide.
• Mac Mouse Fix: run Uninstall from the app's menu.
• Others: consult the vendor's uninstall docs.

Verify with the same Diagnostics Center step as Option A.

Which one should I use?

• Revoke permission — you still want the other tool for something specific (device-level DPI/SmartShift, Options+ Flow, KVM keyboard sharing).
• Uninstall — LinguaX now covers everything you were using the other tool for; you want a permanent clean state.

Input method tool conflicts

Running multiple input automation tools (other IME switchers or input automation utilities) can cause:

• input source flips unexpectedly
• rules feel delayed or inconsistent
• behavior differs by app without clear logic

Isolation test (input)

1. Quit other IME/automation tools.
2. Keep only LinguaX running.
3. Test one app rule and one browser domain rule.

If behavior stabilizes, an input-tool conflict is likely.

Mitigation (input)

• Choose one tool as the source of truth for input switching.
• Disable overlapping automation in other tools.
• Avoid duplicate rules across tools.

Recovery sequence

This order works for both mouse and input conflicts:

1. Simplify LinguaX to a minimal baseline (one mapping, or one app/domain rule).
2. Confirm the baseline is stable on its own.
3. Re-enable other tools one by one.
4. Stop when the conflict reappears, and narrow that tool's scope (disable just the overlapping feature).
