Description Daniel Rindt 2017-01-21 11:19:02 UTC
Description of problem:
Since the last update of the system the bluetooth mouse stops working after login and starting my webbrowser. 

Version-Release number of selected component (if applicable):

How reproducible:
Simply login to your account in gnome, opening a browser let them request a page. Mouse pointer become laggy and finally after a few more seconds it stops fully from moving.

Steps to Reproduce:
1. Login into your account, move the mouse, no issues
2. Open any webbrowser for traffic on wireless
3. HID device stops working after a maximum of 10 seconds

Actual results:
Unable to use the bluetooth pointer. Also BT Audio isn't working. I assume that the whole bluetooth isn't working anymore.

Expected results:
Bluetooth should work.

Additional info:
I can remember at the beginning 2016 there was a lot of issues with bluetooth coexistence with wifi. Since both use the 2.4Ghz band for communication. So far i know there is a flag for the iwlwifi module bt_coex_active which i have played with. Without success this time. In the time ago i used the flag to set that i use both wifi and bluetooth. The option become a default and so the option i had no longer to set to enabled. But for now seems that this feature is completely broken. I had no succeess by undoing my dnf update.
I wasn't able to select the proper component, so i decided to use the generic one. The real package which contains the firmware is iwl7260-firmware.

In the meantime the mouse works again, but isn't usable. The mouse pointer stutters and some movements are not influencing the pointer. Slow down random
makes the mouse unusable. Since i can't reproduce the issue for other bt devices i guess the issue on this layer is solved.

Hi Daniel,

I'm diagnosing a similar issue with my BT mouse setup (I'd for years been using Logi/MS proprietary wireless with dongle). The symptom I have is that at seemingly random times, my BT mouse (Satechi M1) will become very laggy and "disconnected" feeling. It works, but is painful to use. Toggling BT off/on in the UI or via command line (`systemctl restart bluetooth.service`) clears the issue up. 

Does this sound related to anything you saw? I wanted to ask before filing a new bug.
