Before the changes backlight was working fine using the ACPI method: /sys/class/backlight/acpi_video0/ is present and the keyboard function keys control brightness with notifications working in GNOME. In the code as was present in the linux-pm/bleeding-edge tree I would encounter a hard lockup on keyboard brightness trigger. This also occurred with the code as it initially hit mainline, but a later commit fixed the crash*, but resulted in no backlight controls being available at all. /sys/class/backlight is empty. *not actually sure if /sys/class/backlight contained anything before this -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
