My oversensitive touchpad
This is more a note to self than anything else, but who knows, maybe someone reading is having exactly the same problem as me?
The "new" laptop has an overly sensitive touchpad, in that it seemed to be clicking at times when I didn't want it to click. While quite a few people handle this by disabling the touchpad or disabling tap-to-click, I knew from experience with my last linux laptop that this is a solvable problem under linux at least.
There's a *lot* of ways to control mouse settings, but here's the one that worked for me. In short:
to find my touchpad device, which turned out to be id=12
to give me a list of relevant entries
to set it to something that seems better behaved.
According to the link above: "By increasing the second parameter, you require more finger pressure for the trackpad to respond. The first parameter controls release pressure, the third is to detect a button press (I think)."
and that seemed to match up. In my case, I needed to up the second number. While I was in there, I tweaked the two-finger settings so it'd be easier to "right click" with two fingers.
Lest it's useful to me later, here's my current settings:

Re: The Joy of xinput
Seriously, I don't know how people handle laptops without that level of acceleration. i was horrified that one of the backbox settings I tried this time accelerated the pointer so much that it became impossible to close windows because it'd jump too many pixels even when I was going slow. WTH? Who thought *that* was a good algorithm?
You may find that you need to implement the same xinput settings multiple different ways, even if you don't change hardware, because different drivers for the same hardware present different interfaces.
Yup. I'm *quite* familiar with this. Remember, not the 1st linux laptop I've set up!
I ended up configuring each one to behave like the factory defaults of the other, which terribly confuses anyone who tries to use my Macbook.
That's hilarious. :) People have trouble with my macbook because of the high pointer acceleration as is; I can't imagine what they'd do if I had it configured any "weirder" ;)
