I'm trying to use a new PDP Xbox One controller ("Crimson Red"). As is, my Ubuntu 18.10 system doesn't seem to recognize it; its power light doesn't even turn on. Using some hints posted here, I got a copy of xpad.c for my kernel (4.18.0), edited xpad.c to add some lines for my controller's ID (0e6f:02c6), and compiled and installed the module. However, sudo modprobe xpad yields modprobe: ERROR: could not insert 'xpad': Operation not permitted. What gives? The output of sudo modprobe -vvv xpad is:

The solution is to disabled the Secure Boot. Firstly check if SecureBoot is enabled on Ubuntu.
Install mokutil "sudo apt-get install mokutil"
and check the status of SecureBoot "mokutil --sb-state"
In case it is enabled run command "sudo mokutil --disable-validation"
Now enter a temporary password between 8 to 16 digits. We will use this password later. Enter the same password again to confirm. Once it’s done reboot the system and press any key when you see the blue screen (MOK management). Select Change Secure Boot state. Enter the password you had selected before and press Enter. Select Yes to disable Secure Boot in shim-signed. Press Enter key to finish the whole procedure.
Predictably, it was some dumb Secure Boot thing. Once I signed the module with
I could
modprobeit without issues, and the controller works well.The files
MOK.privandMOK.derare Secure Boot keys, which I'd previously created using this answer to get VirtualBox working.
