I have the Nvidia MX 150 graphics card in my Asus S15 Vivobook running Kubuntu 18.04.

After I install the Nvidia graphics driver, everything runs great except that the system does not wake up after sleep. I have tried multiple versions of the driver, from 340 up to 390, but none of these fixes the problem. I have tried all the fixes I have found on different sites, like updating grub, updating the kernel, and a few other hacks. Unfortunately nothing works. Maybe it's an issue with my MX150 graphics card.

You could try this:

Suspend/Hibernation
If you use an old NVIDIA driver, hibernation and/or suspend may not
work. Here is a potential work around:

We need to edit xorg.conf, open a terminal and enter the following
command:

gksudo gedit /etc/X11/xorg.conf In the section called Section "Device"
add Option "NvAGP" "1", you should end up with something like this:

Section "Device"
Identifier "my id"
Driver "my dr"
VendorName "my vendor"
BoardName "my board name"
Option "NvAGP" "1"

EndSection Blacklist the intel_agp module from being loaded by the
kernel. This is done by editing blacklist.conf, open a terminal and
type:

gksudo gedit /etc/modprobe.d/blacklist.conf Then add the following
line:

blacklist intel_agp Reboot your system.
