DESKTOP_SESSION is created by the display manager. In particular, SDDM puts an absolute path in DESKTOP_SESSION, which seem to be quite distinct from what other managers are doing. I have opened https://github.com/sddm/sddm/issues/852 about that matter.
However, the 60x11-common_xdg_path could be made to produce better XDG paths. This scripts was created by Ubuntu (see https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/804734 for the context), so Ubuntu should fix it if need be. Note that nothing says the paths in such variables have to be valid. The users of these variables should be ready for invalid path (simply switch to the next one in the list). ** Bug watch added: github.com/sddm/sddm/issues #852 https://github.com/sddm/sddm/issues/852 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1668722 Title: 60x11-common_xdg_path uses $DESKTOP_SESSION which needs a sanity check Status in xorg package in Ubuntu: Confirmed Bug description: This file: /etc/X11/Xsession.d/60x11-common_xdg_path contains references to $DESKTOP_SESSION variable. On one of my Ubuntu installs this variable contains: "plasma", on the other it contains: "/usr/share/xsessions/plasma". I don't know where either example comes from, but the upshot is that paths are added to XDG_DATA_DIRS and XDG_CONFIG_DIRS that don't exist. MANDATORY_PATH is also affected I believe, maybe others. Surely a sanity check of the generated paths is in order. Seems pointless to add non-existent ones. $XDG_SESSION_DESKTOP looks like a replacement for $DESKTOP_SESSION, but is that true? Cheers!
