I am not sure GDM is really the problem. On both computers, I am using lightdm, in my case, lightdm is surely not the problem (it could be a different configuration of lightdm, I could dig into lightdm documentation but it seems rather small). > bash automatically reads /etc/profile when invoked as a login shell. > There are more details here: > > > https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html > Yes and I can confirm it works. That said, a mechanism to always invoke bash as login shell could have side effects that I may find only much later. Or, after an upgrade, that mechanism may stop working, or create other problems, and I could have forgotten what I did manually. Perhaps the problem even comes because of something I did manually and can't remember. If anyone is using Guix with Debian 11 and Mate, I am interested to know whether that problem exists or not.

I had a similar issue recently on my Ubuntu laptop, when I switched the display manager from SDDM to GDM. From what I gather, the latter launches the desktop session without using a shell so at no point the shell initialization files are evaluated and thus the environment isn’t set up as usual. I use KDE Plasma, and it has a mechanism to evaluate shell scripts to set the environment, so in my case to fix the problem what I had to do was: $ ln -s /etc/profile ~/.config/plasma-workspace/env/profile.sh I searched a bit, but unfortunately I couldn’t find an equivalent solution for MATE. I suppose one alternative would be to switch from GDM to SDDM. :-) > Does guix configure another file to set environment variables properly > or is /etc/profile.d/guix.sh the only one?

Initialization of environment variables for guix on foreign distro
Hi everyone, On Trisquel with mate on my laptop, when opening a mate terminal (the command is just "mate-terminal", no option), all the suitable environment variables for guix are set. On Debian with mate on my desktop (I had problems with Trisquel that I could not solve for one year so I am using Debian), when opening a mate terminal, the suitable variables for guix are not set. So I am searching how to fix that on the desktop with Debian. On both computers, there is /etc/profile.d/guix.sh with the same contents. On the desktop, "bash -l" sets all the environment variables properly for guix properly, but I'd like to start programmes installed by Guix from the mate menu too. Does guix configure another file to set environment variables properly or is /etc/profile.d/guix.sh the only one? Is it supposed to be sufficient to source it via /etc/profile? If sourcing /etc/profile is supposed to address all cases, what is the recommended way to have it sourced? (on the laptop, I searched all .* files in my home directory, none of them is sourcing /etc/profile). That last question is not guix-specific but any advice is still welcome.
