Hi all, looking for help diagnosing bluetooth mouse lag. I'm using a Logitech MX Anywhere 2, I've had it a few years now and it's worked well on a number of Linux distros. I recently installed Debian 10 and set it up to use Sid repos. In this environment, the mouse does not work as responsively as normal. I'm on a laptop, and the touchpad works perfectly smoothly, and a wired mouse is also perfectly smooth. What I get with the bluetooth mouse is as if the sampling rate is maybe once every 3 or 4 frames.
I still have Pop!_OS installed which is based on Ubuntu 19.04, the mouse works as expected in that environment. Forgetting the mouse and re-adding it offers no change to behaviour, same with reboots. I've updated to the latest state of the repos, no dice.
My best guess would be that it's down to the iwlwifi module (it's a Lenovo Yoga 900 with an Intel Core i7 6560U with integrated Intel Wireless 8260), but no idea where to go from here.
Cheers!

Bluetooth Mouse Lag
Re: Bluetooth Mouse Lag
Why would it be something to do with the iwlwifi module if it's a bluetooth device?

Re: Bluetooth Mouse Lag
It was my understanding that the module deals with bluetooth too. Am I mistaken?

Thanks for sharing, I should have mentioned I am using non-free firmware, not much extra info on that page although I did try the 'slow wifi' solution with no change to mouse speed.phenest wrote:https://wiki.debian.org/iwlwifi
I should also mention that I found another solution that suggests switching to Xorg instead of Wayland, again no change in behaviour when I make the switch.
