My appoligies: It turns out I forgot an update-grub after reverting the kernel parameters. Can/should the attached debug files be removed or replaced? Please let me know :)
And please ignore all remarks about the default interface remaining gone. It's back and called acpi_video0 ... Also the hotkeys are working again and the showkey output is: Fn+Left: 0xe0 0x4c 0xe0 0xcc Fn+Right: 0xe0 0x54 0xe0 0xd4 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1309462 Title: Intel Ivybridge Mobile graphics backlight not adjustable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1309462/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
