Same problems here... if I boot with acpi on, I can change brightness only using the nvidia-settings. Other hotkeys work fine (Fn sound up/down for example, or switch on off wireless).
I have the flickering with all gl applications so maybe its related to the nvidia driver. -- backlight brighness control does not work (Samsung Q45 with Nvidia GForce 8400M) https://bugs.launchpad.net/bugs/146710 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
