My understanding is that windows are moved withint a screen using Win+Arrow and across screens with Win+Shift+Arrow. I would like to unify this, to move windows around without pressing shift.

In Windows, it it possible to move a window to, e.g., the left edge of a screen with Win+Left. A subsequent Win+Left press then moves it to (the right edge of) the monitor to its left. I find this simpler and also substantially quicker. Is it possible to replicate this behavior?

Alternating pressing shift is rather burdensome for me, as my fingers are not as quick and flexible as they used to be, and neither is my brain, for these split-second tasks that happen a thousand times every day.

I want to take a screenshot. In Windows, that's a simple Graphics::CopyFromScreen call.

In Linux, I feel a little confused on how to do this. It seems there is a principal and stark distinction between X11 and Wayland, so I have to include both code paths. For either, it seems there is quite a lot of boilerplate code, often tagged as 'may break depending on your configuration, good luck'.

Effectively, what I found is recommended most often is to call ffmpeg to let it handle that. I'm sure that works, but I find it rather unpalatable.

I find this strange. Taking a screenshot is, in my mind at least, supposed to be a straightforward part of a standard library. Perhaps it is, and I just completely missed it? If not, is there a good library that works out-of-the-box on most variants of linux?

Update: Thank you all for the input. I eventually went with calling ImageMagick. It is fast, easy to use, well documented, and supports capturing arbitrary displays with little effort.

Same post was allowed when the phrasing "... let ffmpeg do the job" is changed to "let ffmpeg handle it". So the removal seems to be purely keyword-based, in a resoundingly stupid fashion.
