eeepc-laptop tries to expose fan control using a very non-standard API that don't work at all on new EeePCs. eeepc-wmi does not try to do that, so fancontrol don't have anything to control. > If I understood it correctly, the option "acpi_osi="Linux" is activating the > oder ABI, and leaving it, will force the newer one. That's it. Did you check for any fan related option in your bios ? Is your bios up to date ? -- Corentin Chary http://xf.iksaif.net _______________________________________________ Debian-eeepc-devel mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/debian-eeepc-devel
