you’re running way too old a distro for what you want. debian 12 has its merits as a server, you install it and leave it be and it just works.

what you want - fluidity with power management, dock/undock, etc - although achievable with tweaking this and that isn’t being worked on, not on X, not on debian 12, so it’s not like those things will eventually get there. so you need a semi-modern distro, like ubuntu or fedora or even trixie.

wayland isn’t new, it’s default on a lot of distros since 2021 or so, so you can be sure that your use case was previosly met and solved. costs you nothing to boot e.g. F42 off a USB and try it out (has to be 42 as earlier live sessions default to X11). if you have lots of RAM, add the rd.live.ram switch so it copies the image to RAM and everything is super-snappy for testing and it doesn’t touch your SSD.

gnome sushi (installed by default in gnome) handles the press space to preview file. not a fully fledged editor but still miss the thing in plasma.

raspberries were viable while those were cheap. I think I got a 3b (plus?) in pre-deficit years for like $25 second-hand AND I got some shitty case AND a microSD card AND it could run off of a somewhat normal USB phone charger. so using those instead of a 10 year old decommissioned desktop was an awesome value proposition.

nowadays, those devices are encroaching on trip-digits territory and the power adapter is like $30. the computing power you can buy for a third of that designates raspberries exclusively for niche use cases where footprint and power consumption are primary considerations.

not to mention fake Jason Statham just rubs me the wrong way, like all them “visionaries”. he makes this sound like he’s the head of Feed Africa or something, on a noble mission to save humanity and whatnot.

you can remove firmware and other software that doesn’t pertain to your system. the regular upgrade process will be shorter and you’ll save some SSD space.

however, you’ll lose the ability to take this SSD and plug it in a completely different system, like e.g. an intel laptop, and have it boot right up, unmodified.

for future reference, encrypt your drives from the get-go. even if it’s not a mobile device, you can use on-device keys to unlock it without a pass-phrase.
