It appears the problem is that you have
partially/unsuccessfully/manually installed the Nvidia graphics driver
but it's no longer installed and it has left the 'nomodeset' flag in
your kernel command line:
ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-24-generic root=UUID

Thanks for the prompt response. I removed 'nomodset' and ran 'sudo
update-initramfs -u' but still the secondary monitor is not detected. In
Display setting it shows 'Unknown Display'.
I've tried selecting the 'nvidia-driver-390' from software & updates >
additional drivers but still no luck.

In comment #5 it says "No proprietary drivers are in use".
Please try changing the option in that dialog and back again, then click
"Apply Changes".
After rebooting if the problem is not solved then please run 'apport-
collect 1781125' to send us newer system information.

Thanks. It appears you now have the Nvidia kernel driver installed OK,
but the Nvidia X driver isn't being used at all.
Please run:
dpkg -l > dpkgl.txt
and send us the resulting dpkgl.txt.
Please also see if you can find one of these files:
/etc/X11/xorg.conf
/etc/xorg.conf
and if so then a
I've tried many times to apply one of the available Nvidia drivers (390,
396) but still it displays that "No proprietary drivers are in use".

Thanks for the prompt response. I've deleted the
/etc/X11/xorg.conf.failsafe and restarted the laptop. But still I cannot
set a proprietary driver and cannot plugin a secondary monitor.
Given below are the only two driver versions that was available as I updated

OK.
Deleting xorg.conf.failsafe was just the first step required. I think it

You might next need to create a new file:
