我正在运行一台联想笔记本电脑。我已经有一段时间遇到驱动程序问题了，并且计划在有时间时重新安装 Linux Mint，并且可以确保它不会干扰我的大学课程。这是命令“uname -a”的输出：
Linux $NAME 3.16.0-38-generic #52~14.04.1-Ubuntu SMP 5 月 8 日星期五 09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
出于隐私原因，我省略了计算机的实际名称。在我开始遇到这个问题之前，我想在启动时关闭蓝牙连接，因为它会自动打开，但我不希望默认情况下打开它。我按照本文中指定的方式编辑了蓝牙配置文件：

我认为我可能搞乱了一些太多的配置选项，所以这里是文件“/etc/bluetooth/main.conf”的打印转储：
[General]
# List of plugins that should not be loaded on bluetoothd startup
#DisablePlugins = network,input
# Default adaper name
# %h - substituted for hostname
# %d - substituted for adapter id
Name = %h-%d
# Default device class. Only the major and minor device class bits are
# considered.
Class = 0x000100
# How long to stay in discoverable mode before going back to non-discoverable
# The value is in seconds. Default is 180, i.e. 3 minutes.
# 0 = disable timer, i.e. stay discoverable forever
DiscoverableTimeout = 180
# How long to stay in pairable mode before going back to non-discoverable
# The value is in seconds. Default is 0.
# 0 = disable timer, i.e. stay pairable forever
PairableTimeout = 0
# Use some other page timeout than the controller default one
# which is 16384 (10 seconds).
PageTimeout = 8192
# Automatic connection for bonded devices driven by platform/user events.
# If a platform plugin uses this mechanism, automatic connections will be
# enabled during the interval defined below. Initially, this feature
# intends to be used to establish connections to ATT channels.
AutoConnectTimeout = 60
# What value should be assumed for the adapter Powered property when
# SetProperty(Powered, ...) hasn't been called yet. Defaults to true
InitiallyPowered = false
# Remember the previously stored Powered state when initializing adapters
RememberPowered = false
# Use vendor id source (assigner), vendor, product and version information for
# DID profile support. The values are separated by ":" and assigner, VID, PID
# and version.
# Possible vendor id source values: bluetooth, usb (defaults to usb)
#DeviceID = bluetooth:1234:5678:abcd
# Do reverse service discovery for previously unknown devices that connect to
# us. This option is really only needed for qualification since the BITE tester
# doesn't like us doing reverse SDP for some test cases (though there could in
# theory be other useful purposes for this too). Defaults to true.
ReverseServiceDiscovery = true
# Enable name resolving after inquiry. Set it to 'false' if you don't need
# remote devices name and want shorter discovery cycle. Defaults to 'true'.
NameResolving = true
# Enable runtime persistency of debug link keys. Default is false which
# makes debug link keys valid only for the duration of the connection
# that they were created for.
DebugKeys = false
# Enable the GATT functionality. Default is false
EnableGatt = false
