apport information ** Tags added: staging
** Description changed: After upgrading to Saucy, on my Lenovo IdeaPad Z570 with Intel HD Graphics 3000, it is no longer possible to control the LCD brightness using the hardware brightness control keys. Likewise for the KDE power management settings or the battery icon on my Kubuntu Plasma tray. (I don't use GNOME/Unity.) Until Raring I did not have this problem. There is a workaround available from http://askubuntu.com/questions/362894/changing-the-brightness-stopped- working-in-13-10-saucy-salamander i.e. doing the following command on a terminal: echo 150 | sudo tee /sys/class/backlight/intel_backlight/brightness where 150 is on the scale of 0 to whatever is given within /sys/class/backlight/intel_backlight/max_brightness. Based on this I wrote a GUI which however needs to be run using sudo/kdesudo/gksudo. I have attached it. Bug #1241745 also relates to the same problem on Saucy but apparently relates to an NVidia driver and I was asked to track this as a separate bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1241745/comments/17 --- ApportVersion: 2.12.5-0ubuntu2.1 Architecture: amd64 DistroRelease: Ubuntu 13.10 InstallationDate: Installed on 2013-10-19 (38 days ago) InstallationMedia: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) MarkForUpload: True Package: xserver-xorg-video-intel 2:2.99.904-0ubuntu2 PackageArchitecture: amd64 ProcVersionSignature: Ubuntu 3.11.0-13.20-generic 3.11.6 Tags: saucy Uname: Linux 3.11.0-13-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + --- + ApportVersion: 2.12.5-0ubuntu2.2 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: samjnaa 1717 F.... pulseaudio + DistroRelease: Ubuntu 13.10 + HibernationDevice: RESUME=UUID=ba00d992-e43e-4bce-8689-9647370add15 + InstallationDate: Installed on 2013-10-19 (117 days ago) + InstallationMedia: Kubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) + MachineType: LENOVO HuronRiver Platform + MarkForUpload: True + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=(hd0,msdos9)/vmlinuz root=/dev/sda9 ro quiet splash + ProcVersionSignature: Ubuntu 3.11.0-15.23-generic 3.11.10 + RelatedPackageVersions: + linux-restricted-modules-3.11.0-15-generic N/A + linux-backports-modules-3.11.0-15-generic N/A + linux-firmware 1.116 + StagingDrivers: rts5139 + Tags: saucy staging + Uname: Linux 3.11.0-15-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + dmi.bios.date: 02/22/2011 + dmi.bios.vendor: LENOVO + dmi.bios.version: 45CN28WW + dmi.board.asset.tag: Base Board Asset Tag + dmi.board.name: Emerald Lake + dmi.board.vendor: LENOVO + dmi.board.version: FAB1 + dmi.chassis.asset.tag: Asset Tag + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: 0.1 + dmi.modalias: dmi:bvnLENOVO:bvr45CN28WW:bd02/22/2011:svnLENOVO:pnHuronRiverPlatform:pvrIdeapadZ570:rvnLENOVO:rnEmeraldLake:rvrFAB1:cvnLENOVO:ct10:cvr0.1: + dmi.product.name: HuronRiver Platform + dmi.product.version: Ideapad Z570 + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1255428/+attachment/3980887/+files/AlsaInfo.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1255428 Title: LCD brightness control keys and widget do not work on Intel Graphics on Saucy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1255428/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
