I wondered if there was a set of known gotchas about trying to do any of that stuff, man (9) acpi is a non-existant file so it doesn't look like its heavily documented yet. acpiconf does the 6 sleep modes (cute, that the usage shows 1|2|3|4|4b|5) but there isn't much explanation of them, and it doesn't touch the fan, or the thermal stuff. since the systems config still includes apm controls, I am assuming that we keep both, but people need to be warned|told which are 'safe' and what happens if you enable apm and acpi simultaneously. cheers -George -- George Michaelson | APNIC Email: ggm@apnic.net | PO Box 2131 Milton QLD 4064 Phone: +61 7 3858 3100 | Australia Fax: +61 7 3858 3199 | http://www.apnic.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
