Hello Maxim, sorry to come back to this after so long but this is still a bug I'm still trying to solve how to configure the "environment machinery" on a new Debian 11 laptop, on this machine there is no old user configuration status that could interfere: it's a brand new Debian 11 "basic" desktop Maxim Cournoyer writes: [...] > There are two things that Guix does to help users correctly configure > their system so that Guix installed applications appear on PATH. > > 1.

No, if I remove all the Guix related environment settings from the user ~/.profile (plz see my recent messages in this bug report for details if you need) no environment variable from $GUIX_PROFILE/etc/profile (the file is there) is sourced in the resulting graphical user session: I tried both with LXDE and Mate (via lightdm) That file is sourced and environment variables are properly configured only via a succesful console login (ALT+F1) or an ssh login from a remote machine, I've tried The sourcing of /etc/profile.d/guix.sh is only working if I source that file from ~/.xsessionrc: --8<---------------cut here---------------start------------->8--- if [ -f ~/.profile ]; then . ~/.profile fi if [ -f /etc/profile.d/guix.sh ]; then . /etc/profile.d/guix.sh fi export XSESSION_WAS_HERE="Yes" --8<---------------cut here---------------end--------------->8--- This is the (partial) env after I succesfully login in LXDE, I got it starting LXTerminal from the graphical session: --8<---------------cut here---------------start------------->8--- GUIX_LOCPATH=/home/patrizia/.guix-profile/lib/locale GUIX_PROFILE=/home/patrizia/.guix-profile XDG_CONFIG_DIRS=/etc/xdg/lubuntu:/etc/xdg XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session2 XDG_MENU_PREFIX=lxde- XDG_DATA_HOME=/home/patrizia/.local/share XDG_CONFIG_HOME=/home/patrizia/.config XDG_SEAT=seat0 XDG_SESSION_DESKTOP=LXDE XDG_SESSION_TYPE=x11 XDG_GREETER_DATA_DIR=/var/lib/lightdm/data/patrizia XDG_CURRENT_DESKTOP=LXDE XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0 XDG_SESSION_CLASS=user XDG_VTNR=7 XDG_SESSION_ID=12 XDG_RUNTIME_DIR=/run/user/1001 XDG_DATA_DIRS=/etc/xdg/lubuntu:/usr/local/share:/usr/share:/usr/share/gdm:/var/lib/menu-xdg:/usr/local/share/:/usr/share/:/usr/share/gdm/:/var/lib/menu-xdg/ XDG_SESSION_PATH=/org/freedesktop/DisplayManager/Session2 GIT_EXEC_PATH=/home/patrizia/.guix-profile/libexec/git-core XDG_SEAT_PATH=/org/freedesktop/DisplayManager/Seat0 INFOPATH=/home/patrizia/.config/guix/current/share/info: GUIX_LOCPATH=/home/patrizia/.guix-profile/lib/locale PATH=/home/patrizia/.guix-profile/bin:/home/patrizia/.guix-profile/sbin:/home/patrizia/.config/guix/current/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games GIO_EXTRA_MODULES=/home/patrizia/.guix-profile/lib/gio/modules --8<---------------cut here---------------end--------------->8--- Unfortunately, still XDG_DATA_DIRS is reset to a different value after I login to a LXDE user session (lxsession); please see my recent messages in this bug report for details; so basically I can run all Guix installed application "manually" but they are missing from the menu, also all the mime/type->application associasions are missing in the filemanager I've also opened a thread for this specific issue on debian-user: https://lists.debian.org/debian-user/2022/05/msg00153.html but how XDG_DATA_DIRS is reset after ~/.xsession sourcing is still a great mistery. More unfortunately, if I try to login using a Mate session (with the above configuration, thus with that environment) it fails with this error (via journalctl): --8<---------------cut here---------------start------------->8--- mag 07 09:21:14 raifort mate-session[818]: GLib-GIO-ERROR: Settings schema 'org.mate.session' is not installed aborting... --8<---------------cut here---------------end--------------->8--- If I remove /etc/profile.d/guix.sh from the user's ~/.xsession Mate is able to login with no problems (is this related to GIO_EXTRA_MODULES?) but I miss the Guix environment variables, obviously.
