Comment 57 for bug 1737750

Hi.

I'm following adufray's instructions (https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304/+bug/1737750/comments/13), but the module load seems to fail because the module signature is not right.

With dmesg i found:
 PKCS#7 signature not signed with a trusted key
[ 13.580416] nvidia: loading out-of-tree module taints kernel.
[ 13.580422] nvidia: module license 'NVIDIA' taints kernel.
[ 13.580423] Disabling lock debugging due to kernel taint
[ 13.589541] nvidia: module verification failed: signature and/or required key missing - tainting kernel
[ 13.599431] PCI Interrupt Link [LMC9] enabled at IRQ 21
[ 13.599459] nvidia 0000:00:0d.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=none:owns=io+mem
[ 13.600203] [drm] Initialized nvidia-drm 0.0.0 20150116 for 0000:00:0d.0 on minor 0
[ 13.600231] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 304.137 Thu Sep 14 13:51:03 PDT 2017

The command 'lshw -c video 2>&1 | grep driver' gave me "configuración: driver=nvidia latency=0"

My graphics card identification is:
00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 7025 / nForce 630a] (rev a2)

I can't find how to disable this validation.
This system doesn't user EFI.
Whe I run 'sudo mokutil --disable-validation' it returns
"EFI variables are not supported on this system"
