Ubuntu 14.04 蓝牙鼠标随着时间的推移而滞后

Question

我有

$ 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

和

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

而且我的蓝牙鼠标有时也开始滞后。这种恶化可能需要大约一天的时间，之后它就会停止滞后并正常工作。看起来像慢性病。

它位于 HP-Envy 6-1154er 上。

我在网上发现了类似的问题，但没有得到解答。真是烦人的事情。

有任何想法吗？

Answer 1

在终端运行

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

并重新启动。

蓝牙共存技术iwlwifi不好，让事情变得更糟。
