You can go to "Software & Updates" and then additional drivers tab to check which drivers are needed to be installed.
Or you can use this command to get a list of available drivers:
sudo ubuntu-drivers devices
You can install them manually, or you can use:
sudo ubuntu-drivers autoinstall

1I checked in Software & Updates but it showing No additional drivers are available. Also executed autoinstall command but No drivers found for automatic installation. – Bala Aug 13 '20 at 14:59

In order to fix the touchpad:
sudo gedit /etc/default/grub
Replace line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="pci=nocrs quiet splash"
Save file /etc/default/grub
Execute sudo update-grub
Reboot.
