Good points and it must be emphasized that ~/.profile or ~/.bash_profile are for *login* shells only. Ordinarily shells started from a GUI terminal emulator are not login shells though there is usually an option that can be ticked to invoke the shell as a login shell. > That's interesting, but I'm not sure I fully trust that test you > performed.

I would imagine that Wayland dots it in from a POSIX > shell (the same way the Debian X11 session dots in ~/.xsessionrc from > a POSIX shell). My test was not exhaustive, but I did run your command and with Gnome on Wayland and any variables I had set in ~/.profile appeared in the environment of processes running as my username such as gnome-shell. Trying the same on a Buster VM with Xfce on Xorg showed that variables set in ~/.profile did not appear in the environment of a running process such as xfce4-panel or xfdesktop. Most likely Debian uses dash to source the ~/.profile and ~/.xsessionrc files A quick test shows that Gnome on Wayland does not source ~/.xsessionrc, however Gnome on Xorg does appear to source both ~/.profile and ~/.xsessionrc (tested from a cold start). In this case it is my guess that it is Gnome that is sourcing ~/.profile independent of the GUI environment it is running on. I think this is as far down this road as I care to go! - Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
