After removing sddm and lubuntu-desktop, and using startx to spin up a graphical interface with my window manager of choice (cwm),
~/.local/bin is not on the PATH anymore. I googled around and it seems that this path standard is defined by systemd and if you run
systemd-path, you can see that it expects
~/.local/bin to be on user's path.
What is the standard, desktop-environment-agnostic way to ensure I have the proper environment variables?
Edit to provide more context: I'm using Lubuntu version 19.04, and the default bash shell.
