I retried using 2.6.39-rc4 and now I have two backlight devices: - /sys/class/backlight/acpi_video0 and; - /sys/class/backlight/psb-bl The psb-bl one works, the acpi_video0 one does not. âÂJoost _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/devel
