After reinstalling the latest Ubunt LTS (20.04), I was pleased to discover that the “nouveau” driver for the XServer could manage the dual screen without a glitch. At least for several hours. Amof after several hours the Xserver froze & restarted (it is like a quick crash with all the graphical apps terminated).
So I added the NVIDIA ppa to my package source … and it poposed several possible drivers. A is was unclear which one I must install, I decide to try to download the driver. After selecting all the appropriate options, it downloaded the

NVIDIA-Linux-x86_64-460.84.run

I did not installed it but I selected from the Drivers


The unexpected thing is that it also asked me to install a password

Anyway, I am still with one monitor active ?
How can I enable the second one ?
Starting NVIDIA setup, it seems stuck as it stays EMPTY


!

Any help would be appreciated !

\T,

This might help you: install Nvidia driver on Ubuntu with Secure Boot · GitHub
It is probably because you need to enroll MOK KEY when rebooting your pc with the recently setted password.
The other option is simply to disable secure boot in your BIOS.

Start the manual procedure with the suggested command !

WARNING: Unable to determine the path to install the libglvnd EGL vendor
library config files. Check that you have pkg-config and the
libglvnd development libraries installed, or specify a path with
–glvnd-egl-config-path.


but it seems to hang at 5 % after backing up !

What really amazes me is that I had a working version running & that the XOrg nouveau driver did it perfectly but it was unstable after several hours.

\T,

Looking at the recommendation of the following post

me@Linux01:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

me@Linux01:~$ nvidia-settings

ERROR: NVIDIA driver is not loaded

What is really driving me nuts is that it looks all OK from the UI ? ? ?

Any help to have the second monitor detected as it can be done with the “nouveau” driver.
