Let's not confuse things. This bug is with Lenovo vendor backlight, and is present on the latest kernel.
The guidance on investigating backlight issues recommends using acpi_backlight=vendor. If neither than nor nvidia or nouveau work, then it really doesn't help the situation. Let's see if we can get what appears to be a relatively simple issue fixed - or else, why bother having the vendor option at all :-| -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1516370 Title: Vendor backlight on Lenovo Z580 having random hotkeys issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1516370/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
