Indeed, the X server notices that +its parent process has a handler for SIGUSR1, and consequently sends it +SIGUSR1 when it's ready to accept connections. + +The problem was that SLiM doesn't pay attention to SIGUSR1. So in practice, +if X starts slowly, then SLiM gets ECONNREFUSED a couple of time on +/tmp/.X11-unix/X0, then goes on trying to connect to localhost:6000, +where nobody answers; eventually, it times out and tries again on +/tmp/.X11-unix/X0, and finally it shows up on the screen. + +Patch by L.
