modprobe: ERROR: could not insert 'off': Function not implemented

[dino99]

fresh Utopic installation running a gtx 750 nvidia card, nvidia-331 & nouveau drivers installed, booted with systemd-boot

but :
- software-properties cant find the installed graphics drivers ('additional drivers' tab inside synaptic lp:1369400 )
- nouveau is not listed by lsmod
- if i set 'nouveau' with modprobe, i'm getting:

oem@u32:~$ sudo modprobe nouveau
[sudo] password for oem:

Looks like that issue has already been met and was fixed:
https://bugs.launchpad.net/ubuntu/+source/kmod/+bug/1073062/comments/35

so seems a regression.

Glancing for possible upstream package, Debian Sid has a more recent version which deals with an empty /lib/modprobe.d/ folder like on that Utopic installation. So it seems a good idea to upgrade kmod.

https://packages.debian.org/sid/libkmod-dev
kmod (18-2) unstable; urgency=medium

  * postinst: move any modules parameters from /etc/modules to a new
    /etc/modprobe.d/etc-modules-parameters.conf file. (Closes: #627949)
  * initramfs-hook: do not fail if /lib/modprobe.d/ is empty.
  * Add the man page for kmod(8). (Closes: #665873)
  * Document depmod --show in depmod(8). (Closes: #687435)
