[arch-general] i3 and .zprofile

Hi, I have recently switched from gnome to i3. I really like it, but there are still a few annoying problems left… Currently I use gdm to login; my login shell is set to zsh in /etc/passwd. I have several dotfiles, like ".zshrc" and ".zprofile" in $HOME. The problem is, that i3 does not seem to spawn a login shell correctly (is this even possible?). In gnome3 my settings in .zprofile are applied globally and just fine. In i3 the entire .zprofile is missed. Since .zprofile is sourced by interactive login shells, I guess that there might be a problem. Am I missing something here? Thanks, Stefan
