This forces the server to use the mouse driver (by default on /dev/input/mice) and leave all the hotplugging to the kernel. Does the mouse work then? If not - definitely a kernel problem. </pre> </blockquote> Is that the correct key word for my version? It doesn't like it. Here is that section: Section "ServerLayout" Identifier "layout1" InputDevice "Keyboard1" "CoreKeyboard" InputDevice "Mouse1" "CorePointer" Screen "screen1" AutoAddDevices "false" EndSection It told me AutoAddDevices was an invalid key word for that section. <blockquote cite="mid:20090105005718.GC23481@dingo.redhat.com" type="cite"> <pre wrap=""> </pre> <blockquote type="cite"><pre wrap="">Perhaps someone can tell me either why the mouse protocol will not stay the way I set it or, better yet, why the mouse goes away after using the KVM switch. </pre></blockquote> <pre wrap=""> most likely because your xorg.conf settings are ignored, as they usually are with servers 1.5 and above. http://who-t.blogspot.com/2008/12/evdev-xorgconf-hal-and-other-fud.html </pre> </blockquote> Since I am below 1.5, hopefully this doesn't apply. I don't know anything about HAL. I'm pretty sure my xorg.conf parameters are not being ignored as I have made changes that effect X. But then maybe it is ignoring some and not all. <blockquote cite="mid:20090105005718.GC23481@dingo.redhat.com" type="cite"> <pre wrap=""> Cheers, Peter </pre> </blockquote> <hr />Send e-mail anywhere.
