[Kernel-packages] [Bug 1397088] Re: 1002:6740 [iMac12, 2] No brightness control
Pedro Marques, could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested exactly shown as: kernel-fixed-upstream-3.18-rc7 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Summary changed: - No brightness control on imac 27 Core i5-2500S - ubuntu trysty + 1002:6740 [iMac12,2] No brightness control -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1397088 Title: 1002:6740 [iMac12,2] No brightness control Status in linux package in Ubuntu: Incomplete Bug description: Hello, I have no brightness control on imac 27 Core i5-2500S (poduct model: imac 12.2) running ubuntu trysty with xorg video ati driver. tried to use fglrx proprietary drivers, and end up with black screen and unable to boot. i only needed to low down brightness a little.. --- ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 AudioDevicesInUse: USERPID ACCESS COMMAND /dev/snd/controlC1: pfmarques 2190 F pulseaudio /dev/snd/controlC0: pfmarques 2190 F pulseaudio CRDA: country AW: (2402 - 2482 @ 40), (N/A, 20) (5170 - 5250 @ 40), (N/A, 20) (5250 - 5330 @ 40), (N/A, 20), DFS (5490 - 5710 @ 40), (N/A, 27), DFS DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=0c9bef7b-65b8-41bf-9548-6cf11bdd4059 InstallationDate: Installed on 2014-11-25 (5 days ago) InstallationMedia: Ubuntu 14.04.1 LTS Trusty Tahr - Release amd64 (20140722.2) MachineType: Apple Inc. iMac12,2 Package: linux (not installed) ProcFB: 0 inteldrmfb 1 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-40-generic.efi.signed root=UUID=dba8f74a-366d-4de8-862c-f0118c556c07 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.13.0-40.69-generic 3.13.11.10 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: Home directory not accessible: Permission denied No PulseAudio daemon running, or not running as session daemon.
