Hello Alexander, The light sensor can be used (on mine at least), but nobody had the time to write (rebase) the driver for it. Check these discussions: http://search.gmane.org/?query=ACPI+light+sensor&group=gmane.linux.acpi.devel Basically, it's a standard ACPI light sensor, there was a driver for it, but it should use another subsystem, and nobody did the work so far :). I'll happy to review if you have the time to do that. -- Corentin Chary http://xf.iksaif.net -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
