Second display not working on Linux Ubuntu / Abenezer Belachew

Yet another stumble in Linux land. This time, it's the second display not working on Linux Ubuntu 22.04.4 LTS, the distro I'm currently using.
This is the first time I've had to deal with this issue and it was not fun. At first, I thought it had something to do with the display port cable I was using but that turned out to be a red herring.
When I used the HDMI cable, the issue persisted. So I thought maybe it's the HDMI port on my laptop or the HDMI cable itself but that wasn't the case either since it worked fine when I tried it on a Windows machine.

I attempted several solutions, such as restarting the display manager:

sudo systemctl restart gdm

However, these efforts were unsuccessful.

What finally resolved the issue was installing the appropriate drivers using the following command:

sudo ubuntu-drivers autoinstall

Yay.
