nvidia_backlight.c thinks the graphics chip is connected to LVDS, hence create a backlight interface, 'nv_backlight'.
This can be somehow 'workaround' in userspace tool, but I think it's not the best way to do it - the backlight interface shouldn't be there if it's not working at all. I'll file an upstream bug to ask DRM maintainers how to handle this kind of situation. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1683445 Title: E6430 brightness control not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1683445/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
