I’m installing for a server, there’s a lot I’ll never use (CUPS, play sound/video file, Bluetooth, Email…) I don’t need much, LAMP, (S)FTP, web browser, and a better desktop than Damn Small Linux.
What are the major differences between the two?
Are the other KDE packages recommended?
If it matters openSUSE-Leap-15.6-DVD-x86_64-Build710.3-Media.ISO
I’m not quite a n00b, but this is outside my knowledge.
I did first not understand quite your title, but now I guess that you are talking about the choice you can make rather at the beginning of an installation: TExt only, Minimal X or a number of DEs (not only KDE, but several). I hope my guess is correct.
Depends on what you plan to serve. When the management of the services you want to provide need no GUI programs (just an editor and maybe some CLI tools specific to the service), you do of course need no DE at all and even maybe even a CLI only system.
So it seems that your services at least include a HTTP service (LAMP). One can perfectly configure such a server from the CLI. But then again, it may depend on the contents of the web-server. Of you get delivered complete contents (HTML pages, etc.) from elsewhere or if you need to create them on the same system with some web creator software matters a lot.
In the end it is only you that knows what your system needs and we can only guess.
I prefer Server selection from Network Image ISO, i always install my fav DE KDE from tty, it takes a bit of time to setup as i like, but in the end the result are satisfying when you have the basics clear how things works or are set, you’ll end up with a minimalist system with less bloat from Server.
By the way, use Plasma 6, KDE Plasma 5 was yesterday.
There isn‘t any difference between the available software, patterns or selection of the network or full image (when network connection is up).
I think it dies not matter very much with your more general question, but first tagging a topic with “other”, then saying you use Leap 15.6 and then saying you use KDE 6 (with does not belong to Leap 15.6 at all), might confuse people about what they are discussing with you.
But Server and Full make the difference between what you do yourself and what you are served.
Other internals settings may be identical.
