I have good news! I can play 1st person shooters on the touchpad once again!
I can finally use a product that I spent good money on! What a concept! LOL

I knew that something was off, but I couldn’t pinpoint what it was…
Took me almost 2 months of fiddling around with my new laptop but I eventually found linux commands to “fix” my touchpad and now I can play 1st person shooters on it again. There’s the xinput command but there’s also a less documented one out there, the synclient command (special fine tune settings for the synaptics driver)
With the synclient command, I was able to disable right-click when I have two fingers resting in the touchpad (example: you are running and aiming in game, and you try to press the fire button at the same time… it’s likely that your fire action will not be registered by the mousepad, it will recognize it as right-click instead)
And also reduced the “size” of the right-click button (it is a button-less touchpad, buttons are virtual, defined by software)
These were the commands, for anyone interested:

xinput set-prop 11 300 1, 1, 2

synclient RightButtonAreaLeft=2100

Also worthy of mention, I’m using MX Linux, which is a stand-alone distribution based on Debian that still uses the Synaptics driver (better!!) rather than the libinput driver. I found it to be the best linux distro at the moment when it comes to touchpad mouse movement.

Final observation: I still suck at Quake!! LOOOOOOL
xDDDD
