Comment 6 for bug 599607

Thanks. According to other machines the maximum could also be 0x1ffff. Correct? Nevertheless, to update the driver, I need the output of:
$ cat /sys/class/dmi/id/sys_vendor
$ cat /sys/class/dmi/id/product_name

Regarding your question: No. The driver is supposed to allow to turn off backlight completely. But how many steps do you have? In theory, the range should be 0-0x1ffff and userland tools are supposed to scale to a human-friendly range.

ciao,
Mario
