Hi!

I’m working on msi creator 17m laptop with 1660ti integrated nvidia gpu

W/o any updates installatios my external display stopped working today

Checked some forum topics, used some commands:

```auto
$ nvidia-settings

ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system

(nvidia-settings:7578): GLib-GObject-CRITICAL **: 12:00:43.745: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

```

```auto
$ dkms status
nvidia, 470.82.00, 5.11.0-40-generic, x86_64: installed

```

The logs contain the output of  
lspci -k  
which lists modules available and modules in use. nvidia was available but not used (and also no other one), which has three posible reasons, from most to least common:

1. secure boot enabled and module is unsigned
2. module is blacklisted
3. module is incompatible

So first search fore “secure” in dmesg output leads to the message. (sudo dmesg |grep -i secure)
