I suspect that your problem is caused by the following change in the acpi-support package in Ubuntu 9.10:
* Drop events/video_brightness{down,up}, video_brightness{up,down}.sh: at least some platforms that use these ACPI sequences are seeing them correctly translated to input events, so those users will see duplicate events unless we drop them. LP: #178860. If this is the case, then fixing this for you will require a kernel change. -- brightness keys (Fn+F7 & Fn+F8) on Presario v3425au on hardy https://bugs.launchpad.net/bugs/230421 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
