My touchpad started getting ridiculously sensitive and clicking on things I didn't want it to a couple of years ago, so I disabled the click function which seemed to fix the problem, however it's started getting worse again and every time I put my hand anywhere near my touchpad it clicks wherever the cursor is which means I end up typing in the middle of whatever I happen to be writing which is really rather annoying as I'm trying to do my dissertation.
I've also got a scroll wheel on the front edge of my laptop (which is the stupidest place I can possibly think of for it) which when touched, which is all the time when it's on my lap, disables the keyboard if it scrolls down past mute and then refuses to work until I've scrolled it way up past full volume several times which is extraordinarily irritating when I'm in the middle of writing. I can't find any way to disable this other than physically pulling the wheel out of the motherboard and I'd really rather not do that.
These aren't problems exclusive to Peppermint, they existed on Ubuntu which I was running up until a few months ago. I'm using a 5 and a halfish year old Toshiba Satellite Pro L300 and if anyone has any idea how to fix this I'd massively appreciate it.
