When tmux starts its server, it captures the environment at launch time. Attaching later from a new login leaves WAYLAND_DISPLAY/DISPLAY stale inside panes, causing wl-copy, wl-paste, and xclip to fail silently. set -ag update-environment tells tmux to refresh these variables on every client attach, so clipboard tools always find the correct socket.

DISPLAY is already in tmux's compiled-in defaults. Only add the three variables that are genuinely missing: WAYLAND_DISPLAY, XDG_SESSION_TYPE, and DBUS_SESSION_BUS_ADDRESS. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
DISPLAY is in tmux's compiled-in defaults. wl-copy/wl-paste use WAYLAND_DISPLAY directly so XDG_SESSION_TYPE and DBUS_SESSION_BUS_ADDRESS are not needed for clipboard support. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
