I've searched the web as well as this site (including the other Stack Overflow/Exchange/etc. sibling sites) and have not found any concrete info. I've also searched the official KDE site and have still not found an answer.
I'm running Kubuntu 18.04 on a Lenovo Y7000 laptop with the following:
- KDE Plasma 5.12.9.
- KDE Frameworks 5.44.0
- Qt 5.9.5
- Kernel 4.15.0-128-generic
- Intel i7-8750H
- 8 GB RAM
I had run KMail for several years and I really liked the interface and all of its features. What I did NOT like was the fact that Akonadi and Kontact, etc., seem to be required for KMail to work. KMail was the only component that I ran from this Akonadi mess and I have no desire for any of the other components launching (in the foreground OR background) and stealing resources from my system. Because of this, I had uninstalled KMail, Akonadi, Kontact and several other components about a year ago.
#NOTE: After the removal of these components, I have had no problems; this suggests to me that I had not removed anything necessary for my system to run properly.
My question is this: Can I reinstall ONLY KMail and run it as a "standalone" program, or do I have to have all of these additional, unwanted components install, as well?
Thanks in advance for any help!
Akonadi is an implementation detail of KMail, without it KMail will not work.
Kontact is an app that groups KMail and other PIM applications (like KAddressBook and KOrganizer) into a single application. It is not needed to run KMail, but removing it will not give you any significant benefit
