The installed programs do not have any environments. It is your environment
which will be used at program start. (Or that of Guix because it is what
Guix got at its start, that is on your login)

Sure, but the values from .profile are not active at the moment Guix starts (my
guess).
There may be another file (for instance .xinitrc) which may be evaluated before
Guix
starts.

Hello Zelphir,
I had a similar problem with other window managers, because of not using
.profile.
(I use tcsh as a shell)
I don't know Guix, but it may be the same solution would work for you too.
1.) Edit (or create) ~/.pam_environment (Attached the content of my file)
2.) You need also some packages libpam-runtime libpam0g libpam-modules
libpam-modules-bin
libpam-systemd
(You probably have them already)
It should work with the next login.
