尝试`modprobe xpad`时“不允许操作”

Question

我正在尝试使用新的 PDP Xbox One 控制器（“深红色”）。照原样，我的 Ubuntu 18.10 系统似乎无法识别它；它的电源灯甚至不亮。使用此处发布的一些提示，我获得了xpad.c内核 (4.18.0)的副本，编辑xpad.c为我的控制器 ID (0e6f:02c6) 添加了一些行，并编译并安装了模块。然而，sudo modprobe xpad产量modprobe: ERROR: could not insert 'xpad': Operation not permitted. 是什么赋予了？的输出sudo modprobe -vvv xpad是：

Answer 1

如果您遇到此错误 modprobe: ERROR: could not insert 'rtl8723de': Operation not allowed

解决方案是禁用安全启动。首先检查是否在 Ubuntu 上启用了 SecureBoot。

安装 mokutil“sudo apt-get install mokutil”

并检查 SecureBoot "mokutil --sb-state" 的状态

如果启用运行命令“sudo mokutil --disable-validation”

现在输入一个 8 到 16 位数字的临时密码。稍后我们将使用此密码。再次输入相同的密码进行确认。完成后重新启动系统并在看到蓝屏时按任意键（MOK 管理）。选择更改安全启动状态。输入您之前选择的密码，然后按 Enter。选择 Yes 以禁用 shim 签名的安全启动。按 Enter 键完成整个过程。

Answer 2

可以预见，这是一些愚蠢的安全启动。一旦我签署了模块

sudo /usr/src/linux-headers-$(uname -r)/scripts/sign-file sha256 ./MOK.priv ./MOK.der $(modinfo -n xpad)

我可以modprobe毫无问题地完成，并且控制器运行良好。

这些文件MOK.priv和MOK.der是安全启动密钥，我之前使用此答案创建了这些密钥以使 VirtualBox 正常工作。
