Accidentally uninstalled xorg hwe package and lost graphic interface

I was trying to get a better performance with my touchpad, installing synaptics packages.

sudo apt install xserver-xorg-input-synaptics

It complained about unmet dependencies, pointing to xserver-xorg-core package.

Then I noticed I had different xorg packages installed and tried to switch the mentioned one, by running:

sudo apt-get install xserver-xorg-core 

But then, it started uninstalling xorg hwe stuff, it uninstalled like 9 packages or so.

I then proceeded to install the synaptics packages I needed and rebooted.

No graphics then. Tried to reinstall hwe:

sudo apt-get install xserver-xorg-core-hwe-18.04 (done a cache search to remember it)

was successful, but installed only 2 packages and nothing changed

tl:dr

Do I need to reinstall xorg core hwe packs so I can restore GUI or what?
