I am trying to set Dolphin to manage the desktop in LXQt installed on top of Kubuntu 18, instead of PCManFM-Qt, but this answer says that Dolphin cannot do that, (also this answer) not even on Plasma KDE, but that Kwin does it.
I don't understand exactly if that's correct and what could that mean. As LXQt desktop is installed in Kubuntu, Kwin is installed on my system - and I have set it also the default window manager in the LXQt desktop environment.
What I expect is a folder clicked on the desktop to be opened in Dolphin, and the right-click context menu of a selected file/folder to be the one set for Dolphin - instead of PCManFM-Qt.
I am posting this in order to get a more clear answer.
