touchpad not working for Lenovo Ideapad

I have dual booted my laptop with windows and Ubuntu 20.04. Ever since the installation of Ubuntu, I am not able to use the touchpad.
xinput gives the following output:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PixArt Dell MS116 USB Optical Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ Integrated Camera: Integrated C id=9 [slave keyboard (3)]
    ↳ Ideapad extra buttons id=10 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

I tried removing the xserver-xorg-input-synaptics, but that didn't work as well.
