This is not an xfce4-panel bug per se. It seems that bspwm doesn't even bother owning the WN_Sn (where n is the screen number) selection at all. This is not compliant with ICCCM[1]. This window manager is implemented in a very different way. Regardless, xfce4-panel is designed to run even without a proper window manager. The log messages are a false alarm. panel_application_load_real() is called irrespective of whether a WM was found or not. After testing on unstable, I can attest that both xfce4-panel and bspwm run without issues. Make sure to: 1) Set bspwm as your WM: `xfconf-query -c xfce4-session -p /sessions/Failsafe/Client0_Command -n -a -t string -s bspwm` 2) Have configured both bspwm and sxhkd (God, those names!) If that doesn't do the trick, run the following command: `xfconf-query -c xfce4-session -p /sessions/Failsafe/Client2_Command -n -a -t string -s "xfce4-panel" -t string -s "--disable-wm-check"` This will start the panel skipping the check.
