I use "US International with AltGr dead keys". I'm most used to the US layout, and I need to type in other languages, so this layout works perfectly. I've gotten used to it enough that I just use this layout on every keyboard regardless of what the keyboards say on their keys. The hardest was probably using this layout on on an AZERTY keyboard, I'd often forget where keys were, but it worked well enough.
Yes FreeSync works on multiple monitors, I can't give you a source, I tried it and it worked, but I should say that I tried it on two of the same monitor. I can say that X doesn't play nice on multiple monitors with different refresh rates, so you might wanna go Wayland.
How did you do it? I do it by pushing the base of my thumb down and backwards, and I feel the crack right at the base of my wrist towards the side of the thumb. I suspect I'm actually cracking my thumb, since I'm pushing on my thumb's metacarpal, but I feel it in my wrist.
I can do my knees and toes too, but not consistently. Neck and ankles I cannot. I can crack my wrist though.
I can't crack all joints, but I can crack many. The elbow is the most consistent, but I can crack my knees, most toes and I can also crack my wrist by pulling my thumb backwards.
I imagine things at 2, but if I concentrate I can imagine at level 1.
I can crack my elbows like knuckles by just extending my arms. My brother can do it too, but I've never met anyone else who can do it.
I can do both of those things too, but my ear repressurising abilities aren't that strong, I usually have to either yawn or blow my closed nose.
I can hear CRTs too, but I haven't seen one in so long I don't know if I still can. It was so high pitched I've probably lost the ability to hear the frequency.
I'm not an AI proponent, far from it, but I dont think that's a great argument against AI. AI is a tool like any other, which can be used by "the good guys" or "the bad guys".
I've been through many airport body scanners and I like men, so I guess it's true. ¯\_(ツ)_/¯
