Window manager

In XFCE, it is possible that the window manager (XFWM) does not restart after an update.
This will result in an XFCE session starting with all the windows stuck at the upper-left corner.

This can be fixed by relaunching the XCFE window manager.
xfwm4 --replace

To be sure that this is started correctly when session is launched, add that to $HOME/.xinitrc.
exec sleep 5 && xfwm4 --replace
