When using xinput, you might be on the safer side if you use the property names, rather than their numeric equivalents. The same goes for the device IDs. So your example should read (I'm inventing the mouse name here): xinput --set-prop "My Mouse" "Device Enabled" 0 > > But this mouse is plugged and identified. > Will it be se same thing with a constructor other mouse? > > It is the same thing with keyboard. > But with the <xinput --set-prop 11 127 0> command, I have carriage return > key pressed every time. > > Then, I don't think this solution is ok for me! > Because I think I can't know the new device id for plugged keyboards or > mouse. > > With what I know, I think it is better to set an udev rule. > Am I right? > > Thanks, > Daniel. Again assuming you have a new enough Xorg server (1.8+) you might want to look into using the configuration snippets in /usr/share/X11/xorg.conf.d. Peter Hutterer gave an example of blacklisting earlier on this list: http://lists.freedesktop.org/archives/xorg/2010-October/051405.html In the example he gave a device is blacklisted by name, but in fact you can blacklist an entire range of devices by functionality also: ### /usr/share/X11/xorg.conf.d/01-blacklist-keyboards.conf ### Section "InputClass" Identifier "blacklist all keyboards" MatchIsKeyboard "on" Option "Ignore" "on" EndSection ### For an overview of today's xorg configuration capabilities please have a look at Peter's blog posts: http://who-t.blogspot.com/search/label/xorg.conf, especially http://who-t.blogspot.com/2010/01/new-configuration-world- order.html or the documentation for Fedora at https://fedoraproject.org/wiki/Input_device_configuration. And finally, "man xorg.conf" has some useful information in the InputClass section as well.
