这是一台相对较新的计算机，如果您使用的是 Ubuntu 16.04，那么您没有可以修复该问题的内核更新。
安装 4.6.2 可能会修复此问题。通过运行以下命令下载文件。
wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.2-yakkety/linux-headers-4.6.2-040602_4.6.2-040602.201606100516_all.deb
wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.2-yakkety/linux-headers-4.6.2-040602-generic_4.6.2-040602.201606100516_amd64.deb
wget kernel.ubuntu.com/~kernel-ppa/mainline/v4.6.2-yakkety/linux-image-4.6.2-040602-generic_4.6.2-040602.201606100516_amd64.deb
安装内核
sudo dpkg -i linux-headers-4.6.2*.deb linux-image-4.6.2*.deb
最后运行 sudo restart 重启。如果出现问题，您可以在启动 Ubuntu 时按住 SHIFT 键，重启回当前使用的内核。这将打开 Grub 并允许您选择当前内核版本。
如果 4.6.2 无法解决您的问题，则更高版本的内核可能会解决。对于更高型号，尽管运行了最新的 Ubuntu 补丁，但并非所有硬件都受支持。
