Hi All, I'm using linux 2.6.21, on a Linux Certified laptop (LC2100E). I find that if I do cat /proc/acpi/ac_adapter/AC0/state then an ACPI event for CPU1 is generated (I only have one CPU on my system). More precisely, with acpid running, I see the following line in my system logs: acpid: group=processor, action=processor, device=CPU1, value=00000000, id=00000080 Normally I wouldn't care about an extra line or two in my system logs. However it turns out that if my monitor is idle, then X powers it up every time it receives this event. Thus if I poll the state (e.g. via gkrellm2), I can't put my monitor to sleep! Does any one else have this problem, or know what I can do about it?
