Alt+SysRq+C, although your distro may have it disabled by default.
A fair warning though, safety is relative and crashing the kernel can be destructive. Make sure you have backups when breaking things.
Maybe this is me just being jaded after Nintendo’s fall from grace, but this is the first time I’ve seen a feature and wondered “why”?
If mouse control is important then just let people connect a bluetooth mouse. They’re easy to get ahold of and most people can probably chuck one in their bag if they don’t already have one.
Hell, if you feel the need, just make a “Switch Mouse” with a control stick on the side if you need to. No need to have one controller to rule them all.
I mean, this isn’t illegal or anything. It’s just so situational I’ve only seen it done once (World of Goo for multiplayer). Most people can’t effectively use mice with their non-dominant hand anyway.
Isn’t this just motion controls? The same concept could have been done with the Wii and two wiimotes. Only this time you just wear out the rubber pads on your joycon.
… How does this even work given that a mouse is a precision instrument? Surely the rumble would just cause the mouse to shift around or become less accurate. I think there’s a reason nobody has tried to put rumble in a mouse.
Overall I can see it being a nice emergency feature for if you need a mouse but don’t have one on you. But the fact that they seem to be pitching it as a flagship feature feels odd to me.
Or maybe I’m just being grumpy and this ends up working well.
