All'avvio di xdm vedo la schermata a puntini grigio-neri di X a momenti, cioè alcuni secondi di schermata nera e 1 secondo di schermata "normale" (senza finestra di login).


spulciando il log di xdm ho trovato questo

codice:
Could not init font path element /usr/share/fonts/local/, removing from list!
X Error of failed request: BadDrawable (invalid Pixmap or Window parameter)
    Major opcode of failed request: 14 (X_GetGeometry)
    Resource id in failed request: 0x0
    Serial number of failed request: 491
    Current serial number in output stream: 491

xdm error (pid 8805): fatal IO error 104 (Connection reset by peer)
xdm error (pid 8719): Server crash rate too hight: removing display :0
penso che le ultime due ricghe siano dovute al Ctrl+Alt+Backspace

ravattando nell'xorg.conf ho trovato queste /usr/share/fonts/local/ commentarle potrebbe risolvere?
O rischio di fare altri pasticci?

Grazie
