Bluetooth Mouse Lag
Answer : Solution from reddit from @ashughes in an above comment -https://www.reddit.com/r/linuxquestions/comments/bc15f8/bluetooth_mouse_is_laggy_very_limited_pollrate/ez3ufhs/ sudo nano /var/lib/bluetooth/xx\:xx\:xx\:xx\:xx\:xx/yy\:yy\:yy\:yy\:yy\:yy/info where xx:xx.... is pc bluetooth address and yy:yy... is the mouse bluetooth address. In the file, I added the section at the end: [ConnectionParameters] MinInterval=6 MaxInterval=7 Latency=0 Timeout=216 You may also need to reconnect the mouse. I also tracked this proposal on ubuntu bug here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1824559?comments=all I'm using Ubuntu 18.04 on a Dell Precision 7740 laptop and a Logitech MX Master 3 and had a pretty bad lag over Bluetooth. Setting the parameters as noted in @alenz316's answer did not make a difference for me. However, @Eraph's settings in that thread DID work. I originally found the answer on https://forum.manjaro.org/t/logitech-mx-master...
