Defaults are generally who do not want to understand in depth what they are doing (no offence). Example from other sphere: in R-Cran (used to write statistical models), some functions have defaults to either choose a particular algorithm or an optimisation value. I have heard almost about nobody among students, PhDs and even higher up the ladder, who took the time to understand what is happening below the shell. Instead these people took just the defaults, it worked (result was significant), done. However, if they may have chosen another algorithm, things may have turned differently, which would open up a box with many questions concerning modelling adequacy and understanding of data. It is the same with defaults in Linux.

Can you give 1-2 links, please? Would like to see these guys and what are they saying.

How comes that Vim is proprietary? Jetbrain offers community versions which are afaik open source too, so you can look at the source code, you do not need to pay or agree to an EULA.

Attention Ubuntu users if you haven’t heard about it. There is currently a problem with the update, which is why it is stopped: Release Manager Simon Quigley on Reddit.

IMHO it is at first much more important that the distribution is running well, is safe, and gets the required support so that it can establish itself among the many distros and remains for many many years an entirely European distro! I do not care in the beginning if it is called Donald Duck OS, mc2 Linux or whatever.

I do not have a Slimbook but they look really nice on their webpage. However, I miss the possibility to choose among hardware components like with Tuxedo Computers, which is also located in Europe.

Give it a try. Perhaps they may give you at least a hint.

Pcmanfm? Nemo? However, if one does not need a GUI I would suggest ranger, nnn or alike.

Oh, I did not know about the possibility of replacing xfwm4 with i3. I too am using i3 for some years and like a lot to have a clean surface which facilitates focussing on my tasks. However, never thought about integrating it in a DE.

You mean switching between the DE xfce and the WM i3wm, right? Yep, this works and it can indeed make life sometimes easier to have a DE and a WM aside each other.

I am absolutely with you about i3. Simply great (there is also dwm or qtile)! But it is a WM, not a DE, what OP asked about.

Did you contact TUXEDO Support Centre?
