No HDMI on Ubuntu 18.04 with GTX 1650

Hello,

My HDMI port is not detected on my freshly installed Ubuntu 18.04 on a Asus Rog Strix PX751GT AU124R with Nvidia board GTX1650


$ nvidia-settings

ERROR: NVIDIA driver is not loaded

Please disable secure boot in bios.

It fixed the issue !

How did you see it was the problem ?

Thanks for your help !

The logs showed driver was installed (lspci -k) but didn’t load (it isn’t signed if module signing wasn’t set up). dmesg told “secure boot enabled”. 1+1=2

I have the same problem with 18.04.
I’m using NVIDIA GT 1030.
Secure boot is off.
Prime-select query is nvidia
‘uname -r
5.4.0-89-generic’
I tried 390, 418, 450 and 470 drivers.
