While I am waiting for my new laptop to come, I want to prepare.
As I used Linux (Eos) like year ago, I am out of news and all good things about Linux.
I want stable (not too stable xD) DE, great design. Finally I can ditch Windows 4ever.
Also which file system to use and do I need swap etc ?
They will all work well on any relatively modern hardware and are all relatively stable at this point. Of course, things like mate/xfce are more stable than kde/gnome/cinnamon/budgie because they are getting more frequent changes still.
As long as you avoid Deepin, you should be fine.
I would recommend most people checkout both plasma and gnome since they are the most widely used and represent opposite ends of the spectrum when it comes to most design decisions.
Also, there haven’t been any major DE shifts in the last year so whatever you liked a year ago is probably still a good choice.
It’s important to look at which apps you will use.
If you prefer in majority, QT apps, then KDE/Plasma is the best choice.
If you prefer using GTK apps, Gnome should be the best choice.
Note that QT is not totally free. GTK and Gnome are the liberty choice
Which laptop did you finally order? As for desktop I don’t think you can go wrong with Xfce. But honestly any of the desktops would be good. It depends on what you like in terms of how its works and how you use it.
Xfce - fast, easy to use, but old look
KDE- almost no issues, lot of possibility
Gnome- nice one, like it, but kinda heavy on ram. But now I will have 32gb so
BSPWM- lightweight, complicate to get look what I like but I like keyboard oriented WM
KDE is also a little heavy on ram compared to Xfce but is closer to Cinnamon and Gnome but with 32 GB i don’t see any issues. I also have 32 GB and i do most of my testing with KDE host. The reason i like KDE is using it feels fast and fluid. I like using kate, konsole, yakuake and any packages i want to install work great. I don’t use it with Wayland but you can and it does work well for the most part. Only you can really decide what you like, what you don’t like and what you are willing to put up with if there is something that annoys you about the way it works.
