Could it be a HAL problem?

At some point both > keyboards are seen as the same and removed together. The error message refers to the same device. How is the laptop's keyboard represented? I thought it would have been a PS/2 keyboard, attached to atkbd, not a USB keyboard (as built-in pointing devices are often recognized as PS/2 mice, being represented as psm0, not ums0). Additionally, AT keyboards usually cannot be removed, as they are not hot-pluggable per definition, and in most cases, they aren't even detected - only the keyboard controller is. Can you "dmesg | grep kbd"? Example from my home system: atkbdc0: <Keyboard controller (i8042)> at port 0x60,0x64 on isa0 atkbd0: <AT Keyboard> irq 1 on atkbdc0 kbd0 at atkbd0 There is no keyboard connected, just a lonely HIL plug on the table. :-) The Sun Type 7 USB keyboard I'm actually using can be detached and re-attached in X without problems. If the IBM model M keyboard (can be connected to the HIL plug if needed) is present, it keeps working, no matter if another keyboard is attached or not. NB: I am using X without HAL. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
