Ubuntu 14.04 bluetooth mouse lags time by time

I have

$ cat /proc/version
Linux version 3.13.0-62-generic (buildd@lgw01-59) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #102-Ubuntu SMP Tue Aug 11 14:29:36 UTC 2015

and

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:   trusty

And I have also my bluetooth mouse sometimes starts lagging. This exacerbation can take about one day, after that it just stops lagging and working perfectly. It looks like chronic illness.

It's on HP-Envy 6-1154er.

I have found similar issues on the web, but not answered. It's really annoying thing.

Any ideas?

Solution 1:

Run in terminal

sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=0"

and reboot.

Bluetooth coexistence technology in iwlwifi is not good and makes things worse.

Solution 2:

I am using Ubuntu 16.04 and location is slightly different:

$ sudo cp /etc/modprobe.d/iwlwifi.conf /etc/modprobe.d/iwlwifi.conf.backup

$ sudo echo "options iwlwifi bt_coex_active=0" >> /etc/modprobe.d/iwlwifi.conf

I also tried run the following commands post reboot:

$ sudo modprobe -r btusb

$ sudo modprobe btusb 

Thanks for the original info it seem to work
