This is totally OT so feel quite comfortable with not replying, even if you
know the answer.

I'm running Mdk 9.2 on an AMD Duron with ACPI power management enabled in
the BIOS. I have an ATX power supply and I have Wake On LAN and Wake On
Keyboard enabled. If there is a basic shell in the foreground when the
machine goes to sleep, Wake Up works fine.

I rarely use X but, when I do, it's KDE. If the machine goes to sleep when
the GUI is in the foreground, it can't be woken up, not by keyboard nor by
pinging it. In fact, ping gives no response when it goes into this state.

Does anyone know the solution?
