I've tried that:
Since the -r option ignores configuration files, that warning message looks a bit strange, but I guess the application is nevertheless required to post it.
david@david-laptop:~$ sudo modprobe -r ndiswrapper
[sudo] password for david:
WARNING: All config files need .conf: /etc/modprobe.d/ndiswrapper, it will be ignored in a future release.
But anyhow, it didn't work.
So. If the kernel (the Linux kernel?) won't support removing modules, how do I safely reinstall the kernel? Or is this something I could somehow prevent from happening at bootup?
david@david-laptop:~$ modprobe -l *ndis*
