The kernel is too old to support your intel igpu which drives the internal display. Please either upgrade to Ubuntu 20.04 or install a recent kernel from ppa:
https://launchpad.net/~damentz/+archive/ubuntu/liquorix
I must use ubuntu18.04.06 , because some soft need to run on it
when I run : sudo apt-get upgrage on system ubuntu18.04.06, the kernel is update to 5.4.0.91-generic automatically.
I run the command : apt-cache search linux-image to show the kernel supported on ubuntu18.04.06 , the latest version is 5.4.0.91-generic
add the ppa generix gave you and use apt to select and install a newer kernel.
