I am using a Macbook Pro M1 2021, and only using the built-in trackpad, to run a Linux guest. I understand that Linux/Ubuntu has moved towards using libinput, and that this means that trackpad scroll speed is not customizable. Further, the virtual mouse provided by Parallels is not a trackpad, and doesn't have configurable parameters. It is possible to adjust scroll speed in Firefox. But not for other applications, such as VSCode, or Nautilus. In general, the scrolling experience is barely acceptable, to the point where I would happily switch to VMware if their solution was better, but it's not. Can you please implement trackpad support in Linux/Ubuntu? It works well/smoothly in my Windows guest, equivalent to the scrolling experience on the host. This would provide amazing value for the Mac-Parallels-Linux ecosystem, and keep me as a customer for many years. -- I have tried: - libinput customization - smooth scrolling in the configuration file - "optimize for games". Note that I use side-swiping to change between host and guest (and this works well with Windows), so "optimize for games" is not even an option for me, because it grabs all gestures.
