Bruno Beaufils, thank you for performing the requested test. As a potential WORKAROUND, could you please add each of the following kernel boot parameters individually and advise if you may adjust the backlight: acpi_backlight=vendor video.use_bios_initial_backlight=0
As well, if you remove the nomodeset kernel parameter, does it change anything? ** Tags added: trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190341 Title: [MacBookPro10,1] Backlight stopped working after update of linux-image with nvidia 313.30 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190341/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
