.xsession is sourced within /bin/sh, not /bin/bash. It wouldn’t make sense to source .bashrc from it (unless you happened to write a .bashrc that doesn’t use any bash features).
Also, .bashrc is sourced by _every_ interactive shell, so if you were to add things to environment variables from .bashrc, e.g. PATH="$HOME/bin:$PATH" then they would show up multiple times in shells launched inside shells. This is just an annoyance for $PATH, but it might be an important problem for other variables, so you would need to add code to test whether the variable had already been changed, etc. This is why Ubuntu’s default .profile (see /etc/skel/.profile) sets up $PATH and the default .bashrc (see /etc/skel/.bashrc) does not. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1468832 Title: lightdm sources .profile Status in lightdm package in Ubuntu: New Bug description: It is a bug for any display manager to read .profile--you guys are absolutely killing me with this. The user's .profile is to be read by the shell, on interactive shell (i.e. terminal) logins ONLY. The man page for bash explains this in detail; it's also discussed in the dash man page. The problem with display managers reading .profile is that it is the place where commands to set up your terminal (i.e. stty) go --this is the entire point of differentiating interactive shells from non-interactive shells, and it's the reason only interactive shells read .profile at all. Currently, if you have any such commands in your .profile, lightdm barfs on them, delaying the login session and forcing you to click on a prompt. This is extremely annoying (and wrong)! It would be satisfactory to make lightdm not display the errors, but that's the wrong solution. There's already a decades-established method of getting X display managers to source your environment settings: the .xsession file. It should be read by ALL display managers (or the session file that starts them). If you have common environment settings you want set in all your shells, the correct way to handle this is: .bashrc: # set all common environment vars here ENV_VAR=foo ... .profile: # set up terminal stty erase # BASH already sources .bashrc by default on interactive sessions .xsession: if [ -f .bashrc ] source .bashrc If you're not using BASH, you can still use this method without changing anything, except in .profile you need to explicitly source the .bashrc file. Of course you can change the name of the file that contains the common settings to reflect that your shell is not BASH; since the file is sourced by your other files explicitly, it does not matter what the user calls it.
