Well you simply create the directory before running the program that desires said directory. Does not matter if the user identity change is by way of a system manager, runuser(8), or login(8)/PAM (as called by xdm/etc.). kiosk.service User=npc ExecStart=/home/npc/startx.sh startx.sh: export XDG_RUNTIME_DIR=/home/npc/xdg rm -Rf "$XDG_RUNTIME_DIR" mkdir "$XDG_RUNTIME_DIR" weston # or whatever _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
