More background: processes inherit their environment from their parent process, and so on. Since most of your (user) environment doesn't make sense for system daemons (what is Apache to do with LS_COLORS? But also arguably PATH shouldn't be there, or should, at least, be ignored), there are "checkpoints" at which the (user) environment can be set. Traditionally that happens at login (/etc/profile, ~/.profile and all their shell-specific variations -- sometimes you want slightly different environments for different shells). But X. When X came up, a similar mechanism was introduced, to let programs started directly from X also have nice environments: That is where Xsession (of which there are system-wide scripts in (Debian, at least) /etc/X11/Xsession, typically broken up in task-specific snippets in /etc/X11/Xsession.d -- and user-specific scripts in e.g. ~/.Xsession (or its older sibling ~/.Xsessionrc)). See "man Xsession" and the scripts in /etc/X11/Xsession* -- they are shell scripts and might inspire you. With the advent of desktop environments things have become a bit more complex, but I'm the wrong person for that: I just fled the DE craze ten years ago. Cheers -- tomás
