In my other XPS 13 DE Settings post, I linked to an article about mouse lag that helped my Microsoft 3600 mouse behave better.
Last week I noticed it started acting up again 😔 so I revisited the problem. My previous settings had apparently been wiped out with my upgrade to Ubuntu 20.04. But in my search I found some other settings that might help.
I’m applying both the settings from this post and my previous one, as I feel like the settings in this post additionally help smooth out mouse wheel scrolling.
From this bug report you can also change the latency settings for your bluetooth (BT) mouse. I found it easiest to execute these commands as
root so I could use tab completion to navigate the bluetooth mac addresses:
The BT device info file is at
/var/lib/bluetooth/<BT adapter MAC>/<BT device MAC>/info.
So I type
vi /var/lib/bluetooth/<TAB>EF<TAB>info to get to the right file.
My file started out with these default ConnectionParameters:
[ConnectionParameters] MinInterval=6 MaxInterval=6 Latency=60 Timeout=300
I changed those values to:
[ConnectionParameters] MinInterval=6 MaxInterval=7 Latency=0 Timeout=216
Then I restarted the BT system with
systemctl restart bluetooth
Hopefully this quick tip helps you iron out the kinks with your MS 3600 BT Mouse!
