看看dpkg -l | grep obex
如果没有任何结果,请进入软件中心并搜索 obex,应该有一个在描述中提到蓝牙的结果。
我刚刚在 14.04 上安装了 xubuntu-desktop,遇到了和你一样的故障,直到我从软件中心安装了 obex 包
以下是结果dpkg -l | grep obex
ii libmulticobex1 0.23-1.2ubuntu3 amd64 multi-protocol cable OBEX library
ii libobexftp0 0.23-1.2ubuntu3 amd64 object exchange file transfer library
ii libopenobex1 1.5-2.1 amd64 OBEX protocol library
ii obex-data-server 0.4.6-0ubuntu2 amd64 D-Bus service for OBEX client and server side functionality
ii obexd-client 0.46-1ubuntu7 amd64 D-Bus OBEX client
