Dirk, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .
If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report. apport-collect -p linux <replace-with-bug-number> Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. As well, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream', and comment as to why specifically you were unable to test it. Please let us know your results. Thanks in advance. ** Summary changed: - mute, brightness buttons on new HP 6930p laptop + brightness buttons on new HP 6930p laptop ** Description changed: I purchased a brand new laptop model: HP 6930p with Intel 4500MHD graphics and Intel 82801I (ICH9) HD Audio, and I installed Intrepid with the latest updates. I have the following problems: - The buttons for controlling the brightness (Fn F9/F10) don't work. xev does not show any events for these buttons. Trying to write values into /proc/acpi/video/GFX0/DD0?/brightness has no effect. - Upon connect/disconnect the AC power, there is a little pop-up on the screen indicating that the brightness goes up or down, but there is no change in brightness. - If booted with AC connected, the brightness is high; if booted on battery, brightness is low. This won't change until reboot. - - - Fn F8 is supposed to display a battery status bubble, but it doesn't. - sudo acpi_fakekey 236 has no effect either. When I press Fn F8, xev - reports keycode 244. - - - There is no sound on the built-in speakers. Headset, on the other hand, is ok. - - Clicking the hardware mute button has no effect on the settings in the Gnome volume manager, and muting/un-muting in the Gnome volume manager has no effect on the mute LED. The volume settings, on the other hand, work ok. - - I do not see any of these problems when I boot my older laptop (HP - NC6000) from an Intrepid CD. ** Tags added: needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/284319 Title: brightness buttons on new HP 6930p laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/284319/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
