>So it seems to be reading quite low Yes, this is the experience on several models: MBA11 and MBP41 fall into the same category as your MBP51. The readings are low, but the full span 0-255 is actually used, which can be seen when exposing the sensor for extreme light. The real problem seems to be that neither the kernel nor gnome is equipped to handle sensor readings with such a large dynamic range. For instance, the hal interface used by g-p-m is far too course- grained, only allowing integer percentage values.
>is this something specific to the applesmc driver on MBP 5,1 At least on my MBA11, the behavior is precisely the same. This could most likely be improved upon in the driver, it has just not been done. -- Backlight keeps getting darker on MacBookPro https://bugs.launchpad.net/bugs/285815 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
