Macbook6-1 (GeForce 9400M) Ubuntu 12.04 nvidia-current 295.40-0ubuntu1.1
Works perfectly without nvidia driver (nouveau driver). Attached values of /sys/devices/virtual/backlight. Write random values to any of that files, didn't destroy the machine neither did nothing. Modifications to the default command line arguments to the kernel where made in grub: * reboot=pci # To make the computer restart (before, shutdown -r now just hangs for ever after system shutdown) * acpi_backlight=vendor (Tested with and without without any change). ** Attachment added: "# find /sys/devices/virtual/backlight/ -type f -exec echo -n "{}: " \; -exec cat "{}" \;" https://bugs.launchpad.net/ubuntu/+bug/1006453/+attachment/3277654/+files/output -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1006453 Title: Screen brightness is not affected by keys ("MacBook Pro") To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1006453/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
