Something that I noted in my review of the Google Pixelbook and Chrome OS was a problem with external mice, specifically with the scroll wheel speed/acceleration. I found its scrolling to be a bit too fast for my taste, and while Chrome OS does let you adjust the mouse cursor speed, there aren’t any options to adjust the mouse acceleration speed.

Earlier on in my testing, I recall reading somewhere on a Google Product Forum thread (which I can’t seem to find again anymore) that Chrome OS engineers acknowledged this feature, but turned it down stating something along the lines that it would be “too complex for the end-user.” Fortunately, this seems to be changing soon according to a new Chromium Bug Tracker comment:

“Current state for M78 (once this gets into canary/dev).

You can enable this flag “allow-disable-mouse-acceleration” in chrome://flags and it will add an additional toggle on the Mouse/Touchpad page in settings to allow disabling acceleration. As of right now scrolling is still accelerated.

Future release will remove the flag and make the option available for everyone.”

The comment is pretty straightforward. In Chrome OS 78 for Canary and Dev, users will be able to enable a flag called ‘allow-disable-mouse-acceleration’ which will add a toggle in the Mouse settings page to disable mouse acceleration. In a future release, the flag will be removed and the toggle will be added to Chrome OS.

This issue was first reported in February of 2016 with nearly 150 stars, but, nonetheless, it’s nice to see it finally being added. Let’s just hope it works properly.
