ThinkPad X1 Yoga Gen 7 — Touchpad ghost clicks while typing

OS: Arch Linux
DE: GNOME on Wayland
Symptom: Cursor jumps / ghost clicks while typing, palm touches registering during typing

What triggered it

This started after upgrading on 2026-06-27:

Cursor: Python + Ansible Extension Compatibility

Notes for fixing extension activation failures and Python environment warnings when using Ansible 26.6+, Python Environments, and ms-python.python in Cursor on macOS.

Tested on Cursor ~1.105 (VS Code 1.105 base), macOS arm64, June 2026.

Symptoms

Notification: "Extension activation failed" — root cause is usually ms-python.python

Ralph Wiggum Loop: xhigh vs low effort comparison

Testing the Claude Code agentic loop (claude -p --dangerously-skip-permissions) building a small Python CLI from scratch, with two effort levels compared.

Setup

App: Ralph Wiggum Quotes CLI — random, list, add, delete subcommands, stdlib only
Loop: while grep -q '\- \[ \]' implementation_plan.md — one task per iteration, auto-terminates
Branches: main (xhigh/default effort) vs no-thinking (--effort low)

How to format strings as code w/keyboard shortcuts in various tools:

Slack

inline - cmd + shift + c
block - cmd + shift + e
select any code block, triple click it

GitHub issues and comments - w/Refined GitHub Extension

inline - double click to highlight the string, then press ` to wrap in backticks
block - ??

Usage

Prerequisites

Node.js (v14 or higher)
GitHub CLI (gh) - Install from https://cli.github.com/
GitHub authentication - Run gh auth login to authenticate

Basic Usage

TIL: For a consistent fingerprint auth experience on Mac, for both GUI and CLI, I learned that I can add this snippet to the top of /etc/pam.d/sudo:

auth       sufficient     pam_tid.so

and now everytime I get a password prompt, I instead get a fingerprint popup modal. Saves a ton of time if you have a longer password.

	Whole-GPU utilization sampler via the i915 PMU -- the same source btop and

	engine_util% = delta(busy_ns) / delta(time_enabled_ns) * 100

	This measures the GPU system-wide (pid=-1), so it includes warp's rendering
	AND the GNOME compositor compositing warp's frames -- matching btop.
