当手机连接到 USB 时，如何防止通知和图标弹出？

Question

条件：手机连接到 USB 时出现无关的通知和弹出窗口。
差分条件：USB 电源管理失败，网卡管理失败。
支持：通知、弹出窗口和 dmesg 警告主要发生在电源状态达到最大值时，但在电源状态百分比保持不变时变得相当稳定。

当我通过 USB 将手机连接到笔记本电脑时，文件管理器会一直打开（图 1 和图 2）。左侧栏中也有弹出图标（图 3）。网络共享时还会频繁打开/关闭互联网连接通知（图 4 和 5）。劣质电缆会增加这些烦恼的频率。所有类型的通知每分钟可以发送多次。当电池达到高功率状态时，它们的速率会增加，但在电池充满电时保持稳定。

• 我做了 wjandrea解决问题的建议 ，它的状态在这里。gsettings set org.gnome.desktop.media-handling automount-open falseautomount-opendmesg | tail

仅将设备连接到笔记本电脑时，您会看到大约 10-30 个错误窗口（图 1 和 2）和手机的右侧图标来回弹出（图 3）

• 我做 wjandrea 的第二个建议gsettings set org.gnome.desktop.media-handling automount false。然而，三星手机的图标开始一次又一次地在左侧栏中弹出。它主要发生在我的笔记本电脑充满电时，因此它可能是电源管理中的问题。它的dmesg | tail状态在这里（也参见图 3），这是第一次发生，主要是当我的笔记本电脑达到最大电池状态时。

此处是第二个 dmesg 的子集

dconf是在这种情况下进行检查的地方。

dconf 是一个低级配置系统和设置管理。其主要目的是在还没有配置存储系统的平台上为 GSettings 和 KSettings 提供后端。这取决于 GLib。它是 GNOME 3 的一部分，是 GConf 的替代品。~维基百科

为此，您需要安装dconf 编辑器，如下所示：

sudo apt-get update
sudo apt-get install dconf-tools

要打开dconf 编辑器，

按 Alt + F2

或者

转到应用程序 > 系统工具 > dconf 编辑器

现在在 dconf 编辑器的侧边栏中

org > gnome > 桌面 > 媒体处理

取消选中自动挂载打开选项。

以下是 16.04 中 dconf-editor 的屏幕截图：

我的一加一也有类似的问题，它的 USB 插座有点不稳定，这使得它每 5 分钟左右就会启动一个 nautilus 窗口。

我发现防止这种情况的最有效方法是通过匹配 USB 供应商和型号 ID，然后将设备设置为未经授权的模式，使 udev 完全忽略它。通过这种方式，您可以专门防止该设备触发任何更上游的事情，例如自动挂载，而不会影响其他任何事情。
