since you asked, I'll try to give a sincere answer.
Point is, I won't be of much help here. I have an environment that works. That is MacOS with drivers supported by Wacom. I prefer Linux for other tasks, but that's not the issue here.
You mention "properly compiled & configured" kernals... Do I bother? No.
Do I want to invest hours of my time trying to accomplish something I already have? No.
As someone pointed out, the Win version of PS is better now than the Mac version (used to be opposite). If I need to, I'll move to Win, practical solution.

So, conclusion is: you want to accomplish something, chose the proper tool. One that works. If you are just playing, play. And play as much as you can, it will help you to chose the right tool later when you need it.

In my case, one example: Photoshop with a Wacom tablet.

And no, I'm not going to invest hours or even days to find drivers etc. for a workaround.

I doubt Darling will provide that either, but one still can hope. Anyway, I'm sure other will find more (and better) examples.

Wow. I didn't know Groucho Marx was also a particle physicist ;)

On the contrary. If I had the chance to go to Mars today, I'd take with me:
A recent newspaper, a can of beer and a half-eaten sandwich.

Then I'd place them somewhere were Curiosity was likely to spot it, and return to Earth silently.

And probably run around with a huge grin on my face for the rest of my life.

Short answer: no, since in their world our -5 would be their +5 (and vice versa).

Long answer: you are talking about parallel universe(s) which could exist in a mathematical model.
However there is no way we can prove or disprove the existence of such a world, the same way we cannot know what happened before the "big bang" or what's outside of our universe.

Personally, I'd prefer the double slut experiment.

Exactly. Two more simple examples:
1st: Pythagoras
a^2 + b^2 = c^2. Let a = 3 and b = 4.
Which leads to c^2 = 25, result is +5... Not quite: (and congrats to those who could follow without a calculator ;-)
There are two results, +5 and -5 mathematically, however, only one, +5, makes sense in a physical world, since there is no negative length.

2nd: Give me a few (hundred?) years and I'll come up with a mathematical model where the sun, planets and the rest of the universe is circling around the earth.
It wouldn't make sense whatsoever, but mathematically it still would be true.
