In general it sounds like you want ‘tiling’. There are multiple window managers that does this, e.g. AwesomeWM, i3, Sway, River etc.

Additionally you typically have ‘tiling scripts’ that work on top of Gnome and Kwin (Plasma), however unsure what the capabilities are there.

I can atleast speak for Sway:

Here you can can move/select the current focused window relative to whatever key strokes you prefer, the defaults are using Vim-bindings, but arrow keys are also pretty common.

For grabbing a specific window (like in an ordered manner) is probably something that you would need to extend through scripting if the ‘basic’ movement isn’t enough.

Note: A tiling window manager is quite different (in usage) from a stacking one (which is what one is mostly used to) tiling capabilities/scripts

Are you by chance using an integrated GPU?

Noticed that my AMD Radeon 680M uses quite a lot of RAM as shared memory.

Using something like amdgpu_top will show how much RAM your iGPU is using, metric is ‘GTT’

The whole downside is that not everyone is a data horder with space for videos

Some media players allows for streaming directly using yt-dlp, e.g.;

mpv <youtube url>

Will use yt-dlp if installed

Not what I expected, good thing you managed to get it solved!

That dump didn’t reveal any particular useful information, however it seems like multiple people are reporting issues with mesa + segfault, e.g. https://bbs.archlinux.org/viewtopic.php?id=301550

Mesa v24.3.2-1 in Arch should revert that issue, Mesa v24.3.1 seems to be the problem one

You could check the backtrace of one of your crashes

coredumpctl debug
> bt

And then dump that trace here

It might be related to Mesa/GPU drivers

If all nodes are connected through ethernet to each other (or at least one common node) you could go for OpenWRT’s ‘Dumb AP’ setup as well

Maintainer has been absent for some time so kernel v6.11 and v6.12 isn’t supported OOTB, to get it to work with kernel v6.11 you need to pull the fix from: !48
