Any advice? does uinput-python work for non-privileged users?\n\n\nedit:\n- Debian 12 (bookworm) 64bit\n- Gnome 43.9\n- Wayland (This is why I'm looking into uinput-python, pyautogui doesn't work with Wayland) \n\nDave.","author":{"url":"https://github.com/damies13","@type":"Person","name":"damies13"},"datePublished":"2025-07-11T07:35:23.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/9/python-uinput/issues/9"}
