This strikes a vague chord in my mind but I can't pin it down. In the xorg.conf machines with pc keyboards report the same device driver for the keyboard as the machines with usb keyboards. Does this make sense? I am back to keyboard locking problems. It seems to me it must be caused by the software (presumably the keyboard device driver) failing. Does that make sense? However, if a keyboard is absent the BIOS generates a missing keyboard error which seems ti indicate that a BIOS routine is handling the keyboard. Does anyone have this straight in their minds and can explain it? -- ======================================================================= It is not enough to have a good mind.
