We've got a handful of PC's in a small office running Linux. We switched from MDK91 to SUSE93 over the past few months. One of the machines tends to lock up if left unattended too long. System never had these problems under MDK91. Sometimes (not every day), the monitor will display a message indicating that there is no signal from the computer (freq out of range). We get the same message when the monitor is on, but disconnected from the computer. Please note that the message does *not* come from SUSE, it comes from inside the monitor. Anyway; whenever this message is on the monitor, the system will not "wake up" when we move the mouse or click a key on keyboard. However; the case does still have power. We are forced to power cycle to reboot system to get it working again. The system does not lock up every morning (after being idle overnight). Sometimes it is usable in the morning, but is locked up after lunch (after being idle a few hours). I realise that this type of random symptom can be hard to diagnose, but any ideas why the system does not wake up?
