But if I open the lid, the screen powers off until I swap virtual consoles between X and normal consoles. So when I want the screen to turn off, I open and close my notebook twice. :-) There seems to be a message here that syscons and other bits need to learn more about dpms, and that acpi needs to provide the necessary events (and time) to the device tree to allow proper power management (and may not currently do that). This came up a number of times at the dev summit last week. Robert N M Watson FreeBSD Core Team, TrustedBSD Projects robert@fledge.watson.org Network Associates Laboratories
