我在 Yoga Pro 笔记本电脑上运行 Linux Mint 17.1 Rebecca。笔记本电脑只会进入待机状态一次，然后直到重新启动才会进入待机状态。尝试待机时，它会冻结 20 秒，然后重新启动。pm-suspend在命令行上运行没有显示任何输出。dmesg有一些有用的日志。相关部分如下

root 14665 0.0 0.0 4440 716 ? D 15:20 0:00 /bin/sh /usr/lib/pm-utils/power.d/usb_bluetooth true
我已经尝试过：
rfkill block bluetooth和service bluetooth stop并将它们都添加到但/etc/rc.local没有效果。
我还添加了blacklist btusb和blacklist bluetooth/etc/modprobe.d/blacklist.conf
这些似乎都不起作用，因为 usb_bluetooth 任务仍然启动并且笔记本电脑不会进入待机状态。
我也尝试过，但由于某种原因apt-get purge libgnome-bluetooth11试图删除......network-manager-gnome
如果蓝牙能用就好了，但我只是想让我的电脑处于待机状态......来吧......
