  • It’s my personal top candidates in the order of my preference (best to worst) from my notes when I was researching this topic for my parents. (funnily enough, they ultimately settled on kdenlive, despite not being very computer proficient, because they found more step by step yt guides for what they wanted to do with it)

    All still actively maintained.

    I played around with each of those for a bit some time ago and they were quite similar, so you can pick by your personal preference.








  • to me that smells like what I said in the other comment:

    Wayland might be a bit stricter when it comes to following specs and not implementing hacky workarounds. (or it could always be a bug)

    I feel like, if a cable is high quality and up to spec, it will work with wayland. But if the signal integrity is below spec, wayland might fall back to slower signaling while x11 is more lax and ignores the issue and so a worse cable still works even if unnoticably below spec quality. Or the 4k over hdmi 1.3 is some hack that x11 supports and wayland doesn’t because it’s out of spec.

    But thats just a feeling. May be wrong.

    Thanks for reporting back with your findings!



  • afaik you just listed features that the printer I mentioned (or if I am wrong, other similar printers) supports

    it’s my bad for not mentioning all possible workflows, I was just a bit lazy and thinking of my personal documents only, which do not work well with further smart automation, because my batches are highly irregular. So the more manual approach is the best for me currently. Maybe possible with some future AI integration.






  • The stuff you describe sounds like a cable timing issue. Not something you can fix in Linux. Think of it like the two devices trying to talk to each other on different frequencies and picking the highest res one that works. (so thats why they might get stuck on a random smaller one)

    I had some examples like that in the past where some low quality or very long cables couldn’t reach it’s spec, even fresh out of the box, even on windows.

    Oh, also I am pretty sure HDMI 1.3 does not do 4k at all. Either 1080 or 1440p was the spec limit.

    If you can space the money for an experiment try an active DP 1.2 → HDMI 2.0 cable/adapter.

    Maybe something like https://www.delock.com/produkt/85956/merkmale.html or Digitus branded. Depending on what known good cable manufacturer is available in your area.


  • You can mostly just copy your home partition/dir with something like rsync.

    Step by step:

    1. Install new distro, in the installer make sure to use the same username (otherwise there is some extra work involved but still doable)

    2. start up new distro to make sure it works

    3. reboot into old distro or into live linux

    4. use rsync to copy olddistro/home/user to newdistro/home/user (you have to think about whether it makes sense to overwrite all files or if there is maybe some special exception somehow. Like there may be some idiomatic bashrc on one distro that does not work well with the other)

    (I’ve done that multiple times now and there is some minor fixing involved sometimes, like with the bashrc example, but otherwise it’s super easy. If you ever get stuck just hit me up and I can hop on a Rustdesk/discord/whatever support session)

  • hard disagree, it depends on where you live.

    Which is at the current stage of globalism mostly a personal choise. I have friends that got here by hitchhiking on a container ship by asking the crew nicely and other who literally walked here for half a year, begging for food along the way.

    I moved countries with nothing but my documents and a backpack full of clothes. And I am off way better now, by using my brain and not being an asshole.

    And yeah, bit of survivorship bias, ngl. But it’s far from the bleak picture you drew. If you live in a shithole, go somewhere else.
