Help please.

So, when I came home today I logged into my laptop and did my usual thing, but then when I barely flexed the laptop's touchscreen with my knee (I was laying down) and it started jumping all over the place,  if you had to guess, would it have to do with the wires going through the hinge to the screen?  Or would it have to do with the touchscreen itself?  I want to know whether or not my hypothesis is correct that's all.   Thank you and please reply soon.

did a reboot fix it?

Oddly, it did... however, I don't think it's a software issue---  wait, this is a weird question, how many times could I (theoretically) open and close my laptop's lid before the wires start to  go through their sleeving and possibly bridging wires?

this probably would be a good question for one of the laptop reps

Indeed.   And, I do want to thank you with helping me achieve a solid hypothesis of what the true problem is with my laptop.

You're right, it's most likely a hardware fault. Probably a loose ribbon cable on the motherboard, specs of your laptop seem relatively new, guessing it's roughly a year old. To 100% rule out software/driver issues go into device manager and check and see if your display driver needs an update

There's a slight problem with that, it's not that I won't listen, it's that I am using linux for my laptop.   '-'

As far as it goes to the drivers for this laptop with Ubuntu 16.04 LTS, everything's fine.  Though, I do get the feeling that I may need to replace either the screen or perhaps the palm rest because the keyboard and touchpad are an integrated and single piece (essentially.)   Though, I will see what may be out of the ordinary for my trackpad.

As for my touchscreen, I disabled it with (in my case): ~$ xinput disable 10

Though, it still does that mouse location twitch so I'm guessing even if it could be the touch screen as well or bad wiring.  Although, I did disassemble the laptop's bottom to get access to the motherboard and whatnot inside.   After checking all of the connections, I found that there were no signs of corrosion or any kind of rust, so that's out of the question.
As for the touchpad, could it be possible that if I were to wear it down long enough, would the touchpad react to a "shiny spot" on the surface of the touchpad?

Just curious.

Not one i've encountered yet (partially cause i don't like trackpads), but i'd say you're right about the loose/bad connection. I've seen 100's of laptops with oily keyboards and trackpads (apart from getting grossed out by the grease) they are work fine (keyboards get a little sticky under the keys, but not important (and gross)). Maybe because as it wears down it stops being a 100% level surface and picks up your finger as 2 inputs or the small bits of oil are holding a minute static charge that's messing with the capacitive sensor enough to cause jittering.

I was thinking the same thing as well, however I do have good news.. and... I was a complete idiot to not notice it earlier (or even sooner) but the issue was the touchscreen.   *Insert Le Sigh here.

 

So, I disabled the touchscreen and everything went to normal.  Funny thing is that I rarely if not at all use the touch screen.  The trackpad while it's worn down a bit, works just fine (kudos to HP I guess) and... needless to say, I can keep my cash and I don't have to worry about it at all.

 

Again man, thank you so much with helping me get through the stress of what the "H e double hockey sticks" is going on with my laptop's cursor.
