Ich habe es so konfiguriert kdm(bearbeitet /usr/share/config/kdm/kdmrc), dass automatisch zwei Anzeigen geöffnet werden: StaticServers=:0,:1. Wenn ich mit Ctrl+ Alt+ zwischen ihnen wechsle F7-8, tritt eine Verzögerung von etwa 2 Sekunden auf, was äußerst ärgerlich ist.
Das gleiche passiert, wenn ich startxdirekt von einem aus gehe, ttyohne den Eingriff von kdm. Wenn ich den Fenstermanager ändere (wie openboxoder twm), bleibt das Problem bestehen.
Wie kann ich diesen Wechsel möglichst schnell durchführen?
