First time I see FreeBSD and KDE working and looking so nice, together
I'm impressed - GJ!
You can check KDE PIM Bug Reports and FreeBSD Problem Reports to see if your bugs have already been identified; if not it will help to file a bug report. I did have one "konqueror has crashed" message when logging out (but not while actually using konqueror). I was pleased (so far) to find that kmail worked well for me. Baloo (file extractor) has historically been a pain for many people, but I haven't had any problems there either.I found that PIM stuff and konqueror are very buggy.
Mod4 a :ArrangeWindowsStackRight (Layer=Normal)
Mod4 s :ArrangeWindows (Layer=Normal)
Mod4 d :ArrangeWindowsStackBottom (Layer=Normal)
Mod4 space :ShowDesktop
Probably, I have something outdated experience, since I started to use KDE5 ASAP it landed to official ports, I remember this issues with konquerorI did have one "konqueror has crashed" message when logging out (but not while actually using konqueror).
Now, imagine FreeBSD+ (fer a reasonable monthly donation/subscription ;-) with GUI Desktop (?) and in browser, qt or (?) front-end apps for:
pkg - management
pf or ipfw - firewall configuration/management
jails - configuration/management
Yeah, I know TrueOS used to do some of that. Tho, I have no clue what's their plan for now or the future, seems to me that they're into too many things with not enough resources to do the right thing I'd prefer to see FreeBSD+ with just few, but clean and well functioning GUI desktop apps.
Over time I've found the 3rd party apps I like best for what I consider "everyday desktop activities" and build the same limited number of programs from ports every installation with little variation from one machine to the next. I have my desktops configured to what I consider maximum efficiency for my work style and space available.
Trusting someone else to configure pf for me is out of the question.
If I wanted someone else to decide what 3rd party apps I needed I'd use a DE instead of x11-wm/fluxbox. There would be no need to jump ship to another OS or pay someone to decide what's best for me in their opinion.
Many have criticized KDE for being bloated, and the plasma5-plasma alternative seems to be a fairly successful attempt to address such concerns. Even without resorting to the plasma5 alternative, kde5 has reduced memory usage considerably when compared to its predecessor kde4. The odds are pretty even that I'll never find time to build my own DE by reconfiguring lightweight window managers; I respect and admire such efforts, but I just want something that works well, out-of-the-box so to speak, and Plasma5-plasma has given me that. I've tried out a number of DEs on FreeBSD, including MATE, LXDE, Xfce, and Enlightenment. None of them are quite perfect for my needs but so far the Plasma5 desktop is easily my favorite out of that lot.
Many other "someones" are providing resources for you to try and use, in /usr/ports and /usr/src with "howto" "README" and man pages. Don't they; do you trust them?
I don't care who's done it, what they call their DE or which WM they offer with that DE. But, until I learn (and I never will, b'cause I'm too old and too dumb) to develop, code and test my own WM or DE, I'll trust those who know better, share their knowledge, code and ideas, so others can try, test and use. And then, the users who understand the subject matter and have enough knowledge how things work, may even suggest, a thing or two, to make the Free and Open Source software better. And yes, I'm willing to pay or donate for something that I use and enojy, for Free.
There are too many (nowadays!) kriticks of everyone, anything and everything on Internet and elsewhere. Tho, very few can substantiate their kritikal point of view with intelligent explanation.
