As I said my biggest problem is more people on forums (in general, not here) that simultaniously tell noobs that “Oh all you have to do is to edit /etc/blah/blah.conf” and also say “No nononno! Not like that! it is not SAFE! Shame on you!”.
One thing that Linux is missing though is file managers and text editors (and I am sure this is deliberate) that do like Windows does: Detect a protected file and gives you the option of entering your sudo credentials.
I mean other kinds of programs already does it; be it Mugshot, Timeshift, Yay or Light-dm-greeter. Why don’t make Thunar or Nemo or whatever throw up the same dialogue when you try to copy a file? Or Mousepad when you try to save a file?
This is what polkit is about as far as I know and it’s up to the application to define the allowed actions (again, as I understand it). Not sure why file managers and text editors (as you say) won’t allow some things, but I trust that there must be a reason to this.
One simple command is more complicated than opening a GUI app, searching for the option and clicking on it?
But I guess this thread is already got too much off-topic.
EndeavourOS is based on Arch Linux. And based on the wiki, for security reasons, you really shouldn’t be using DDE. But, it’s your system, do what you want.
Furthermore, please note that this thread is 4 years old.
In the future, please look at the date in which the thread was created, including the last time it was commented on before replying. If the last reply is over 6 months old, it is very likely better to create your own thread and insert a link to the older one.
The point being that the “factual accuracy” of that part of ArchWiki you linked to is under question and based upon that and without further looking into if the bugs have been fixed or not, IMHO, one cannot really come to the conclusion:
You have been around long enough to know you have to do the work.
