I'm excited about very pure and slim desktop environments without unnecessary bloat. In the past I always installed Debian with LXDE as a minimal possible desktop installation considering only inevitably necessary packages to run the GUI like:
xserver-xorg-core
lxde-core
lightdm
network-manager
network-manager-gnome
Now I want to switch to Debian 9 with LXQt. Which packages are at least required for the minimal possible installation of the new LXQt-GUI?
