OS VERSION - Ubuntu 20.04.1 LTS.
KERNEL VERSION- 5.8.0-38-generic.
I am new to Linux. Everything was working fine until all of a sudden when I turned my pc on and a lot of drivers are not working. For example the wifi option has disappeared, trackpad is not working while the external mouse is, keyboard functions are not workin whereas the keyborad is working. I cannot find the option in the settings to control the brightness of my screen and backlight of keyboard.
I have also observed that even animations are not working along with these. Sorry for my ignorance as I am new to this platform
