我是 ubuntu 新手。
我的 lenovo ideapad z50-70 中的 ubuntu 14.04 出现错误：
dmesg | grep -i bluetooth
[ 31.243849] Bluetooth: Core ver 2.17
[ 31.243866] Bluetooth: HCI device and connection manager initialized

我在 askubuntu 中找到了解决方案“将 ath3k 模块列入黑名单echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf，然后在 exit 0 行上方gksudo gedit /etc/rc.local添加，保存，退出并重新启动”modprobe ath3k
但它不起作用。
cat /etc/rc.local | tail -4 的结果
# 默认情况下，该脚本不执行任何操作。
modprobe ath3k 退出 0
结果

@Jeremy31....编辑 /etc/rc.local 后，我得到了
dmesg | grep -i bluetooth

编辑/etc/rc.local文件并输入sleep 20上述modprobe ath3k内容并重新启动
