Hello, how are you friends?
Easier ArchLinux (that many know hehe), it happens that the touchpad of my laptop (Synaptics touchpad) works normal, that is, I pass my finger over the area and the pointer moves, but it does not scroll vertically, not even when I press with a finger on the area is clickable or anything similar.
The fact is that I had to manually configure the touchpad, and here are the steps 😉
1. Open a terminal.
2. In it write the following:
sudo kate /etc/X11/xorg.conf.d/10-synaptics.conf
It will ask for your password, they write it and press [Enter]
3. In the document or text file that will be opened, they must paste this what I left them HERE.
4. Once it is stuck there, they save it and close it.
5. Ready, reboot and you should have the touchpad fully working 😀
If you want to make any changes, questions, questions or whatever, let me know.
