You have some good answers and some bad answers here.

It’s not the fault of the people answering, what you’re asking has been piecemeal and scattershot in implementation over the last decade so everyone has some bizarre response they came up with to be happy.

Allow me to share mine: use a kvm switch.

The switch lets you plug two computers into one keyboard, video, and mouse. But you’re gonna just use the video part. Plug it into both your motherboards and gpus video ports and push the button to switch back and forth between the gpu for gaming and the motherboard for everything else.

Why only gaming? Because everything else you reference can make use of a gpu that’s not being used for video. I guess some game engines support rendering frames and then sending them to another output device but that’s not something to rely on.

So when you’re using blender you see the model on your monitor plugged into the motherboard but the heavy lifting is done by the gpu. When you transcode a video the same thing happens.

I came to this solution after trying to do what you’re asking for in x11 and having a bunch of headaches about it everytime an update would come down.

Pushing a little button on the desktop was easier than messing around with software to make a rube Goldberg contraption to do the same thing. Mine had two leds on either side to indicate which “computer” I was using at the time. I ended up wrapping electrical tape around the rim to cover them both up and cut out the word “turbo” from the tape over the green led that indicated I was looking at the gpu.

If you can figure out how to make a Debian usb installer without help then you’ll be fine.

None of that matters.

You need experience, not recommendations.

Install anything and play with it to learn.

If you will not go forward without a recommendation, Debian is fine and anything you learn will generally transfer to other distributions.

First things first: put real feet on your couch so you’re not doing more damage.

The broader the better.

Some people already talked about ironing and it can make a difference but you gotta get down to the wood surface with sandpaper, learn how to iron wood then successfully actually do it.

Dents as big as these would require multiple passes with the iron over time.

Your real best bet would be to call a handyman or more likely a flooring place and have them give you an estimate on repair. They’ll be able to tell you if you have some kind of tongue in groove, roll or actual hardwood floor and explain what your options are. You’ll also know how much you’re gonna be paying to get whatever the landlord is holding back from them.

If you do call someone out there, find out what they charge for an estimate and pay them more on top of it in cash. People hate giving estimates because it’s someone shopping around who’s gonna try to get them down to the lowest price and has no consideration for their expertise and experience. Being willing to pay in cash and then some cements you as a customer, not a looky-loo.

None of them are grammatically correct because none of them are complete thoughts let alone sentences.

All three try to specify the particular monkey by enumerating that it can see your ears but do no more.

Take away the description of the monkeys ability to see your ears and what you’re left with is “the monkey”.

“The monkey” isn’t a sentence.

If you are the subject and what’s happening is that you’re wondering if the monkey can see your ears then the sentence you want is “I’m wondering if the monkey can see my ears.”

If, as I suspect, you’re using “the monkey whose ability to see my ears I’m wondering about” as the subject of some larger more complex and cool sentence then you gotta lay out that part before someone can give solid grammatical advice.
