[Kernel-packages] [Bug 1516320] Re: Cannot change backlight on my laptop
adam, thank you for reporting this and helping make Ubuntu better. Could you please undo your WORKAROUND and test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel 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 issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, and Y are two numbers corresponding to the kernel version, and Z is one release candidate number if applicable. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Importance: Undecided => Medium ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Changed in: linux (Ubuntu) Assignee: arun (arungpurohit) => (unassigned) ** Description changed: Option stopped working after upgrading to 15.10, full light all time (before with some hacking it was working, but still was lacking keeping - the levels between reboots) + the levels between reboots). + + WORKAROUND: Add kernel parameter: + acpi_osi= ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: linux-image-4.2.0-18-generic 4.2.0-18.22 ProcVersionSignature: Ubuntu 4.2.0-18.22-generic 4.2.3 Uname: Linux 4.2.0-18-generic x86_64 ApportVersion: 2.19.1-0ubuntu4 Architecture: amd64 AudioDevicesInUse: - USERPID ACCESS COMMAND - /dev/snd/controlC0: ab 2051 F pulseaudio + USERPID ACCESS COMMAND + /dev/snd/controlC0: ab 2051 F pulseaudio CurrentDesktop: KDE Date: Sat Nov 14 22:44:57 2015 EcryptfsInUse: Yes HibernationDevice: RESUME=UUID=33abcad5-3750-4855-b97b-2d5b0fb864ee InstallationDate: Installed on 2013-10-24 (751 days ago) InstallationMedia: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MachineType: SAMSUNG ELECTRONICS CO., LTD. 530U4E/540U4E ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.2.0-18-generic root=UUID=f467e962-e87d-4a39-a861-79138b4809d1 ro quiet splash resume=/dev/sdb2 vt.handoff=7 RelatedPackageVersions: - linux-restricted-modules-4.2.0-18-generic N/A - linux-backports-modules-4.2.0-18-generic N/A - linux-firmware1.149.2 + linux-restricted-modules-4.2.0-18-generic N/A + linux-backports-modules-4.2.0-18-generic N/A + linux-firmware1.149.2 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 09/05/2013 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: P07ACM.063.130905.dg dmi.board.asset.tag: No Asset Tag dmi.board.name: NP530U4E-K02PL dmi.board.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.board.version: SEC_SW_REVISION_1234567890ABCD dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: SAMSUNG ELECTRONICS CO., LTD. dmi.chassis.version: N/A dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvrP07ACM.063.130905.dg:bd09/05/2013:svnSAMSUNGELECTRONICSCO.,LTD.:pn530U4E/540U4E:pvrP07ACM:rvnSAMSUNGELECTRONICSCO.,LTD.:rnNP530U4E-K02PL:rvrSEC_SW_REVISION_1234567890ABCD:cvnSAMSUNGELECTRONICSCO.,LTD.:ct9:cvrN/A: dmi.product.name: 530U4E/540U4E dmi.product.version: P07ACM dmi.sys.vendor: SAMSUNG ELECTRONICS CO., LTD. ** Tags added: regression-release -- 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/1516320 Title: Cannot change backlight on my laptop Status in linux package in Ubuntu: Incomplete Bug description: Option stopped working after upgrading to 15.10, full light all time (before with some hacking it was working, but still was lacking keeping the levels between reboots).
