安装 nvidia-387 驱动程序后，我似乎无法再运行 virtualbox。
VBoxManage --version输出：
WARNING: The character device /dev/vboxdrv does not exist.
Please install the virtualbox-dkms package and the appropriate
headers, most likely linux-headers-generic.
You will not be able to start VMs until this problem is fixed.
5.1.30_Ubuntur118389
尝试安装 virtualbox-dkms：
virtualbox-dkms is already the newest version (5.1.30-dfsg-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Linux 标头：
linux-headers-generic is already the newest version (4.13.0.21.22).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
通过清除 nvidia 驱动程序，我可以毫无问题地运行 virtualbox，但明显的缺点是，这样我就无法享受显卡的福利。
您对此有什么巧妙的解决方案吗？我注意到有人提到禁用安全启动，但它已经被禁用了，而且我相信问题出在驱动程序上，因为当我卸载它们时，virtualbox 运行正常。
