+Subject: [PATCH] ui/gtk3: Use XDG_SESSION_DESKTOP for Plasma desktop
+
+If ibus-dameon is launched from systemd, XDG_CURRENT_DESKTOP
+environment variable could be set after ibus-dameon would be
+launched and XDG_CURRENT_DESKTOP could be "(null)".
+But XDG_SESSION_DESKTOP can be set with systemd's PAM.
