Backlight seems completely turned off. Using the brightness keys doesn't help. It was working fine with 3.13.0-34. I found that the offending patch is "drm/radeon: set default bl level to something reasonable". I reverted this patch and recompiled 3.13.0-35, and it solved the problem. --- ApportVersion: 2.14.1-0ubuntu3.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: greg 1962 F.... pulseaudio /dev/snd/pcmC2D0p: greg 1962 F...m pulseaudio /dev/snd/controlC1: greg 1962 F.... pulseaudio /dev/snd/controlC0: greg 1962 F.... pulseaudio CurrentDesktop: KDE DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=fa1d286a-7f50-4e1f-ae6c-9d48161e6c2d InstallationDate: Installed on 2010-07-03 (1521 days ago) InstallationMedia: Kubuntu 10.04 LTS "Lucid Lynx" - Release amd64 (20100427) MachineType: FUJITSU SIEMENS AMILO Xi 2550 Package: linux (not installed) ProcFB: 0 radeondrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-35-generic root=UUID=7b8ed785-f136-4231-b6bd-5e175a9aef0b ro processor.max_cstate=1 radeon.dpm=1 quiet splash crashkernel=384M-:128M vt.handoff=7 ProcVersionSignature: Ubuntu 3.13.0-35.62-generic 3.13.11.6 RelatedPackageVersions: linux-restricted-modules-3.13.0-35-generic N/A linux-backports-modules-3.13.0-35-generic N/A linux-firmware 1.127.5 Tags: trusty Uname: Linux 3.13.0-35-generic x86_64 UpgradeStatus: Upgraded to trusty on 2014-05-08 (116 days ago) UserGroups: adm admin bluetooth cdrom dialout lpadmin plugdev sambashare vboxusers wireshark _MarkForUpload: True dmi.bios.date: 09/30/2008 dmi.bios.vendor: Phoenix dmi.bios.version: 1.15 dmi.board.name: F44 dmi.board.vendor: FUJITSU SIEMENS dmi.board.version: 00030D005503B103 dmi.chassis.type: 10 dmi.chassis.vendor: FUJITSU SIEMENS dmi.modalias: dmi:bvnPhoenix:bvr1.15:bd09/30/2008:svnFUJITSUSIEMENS:pnAMILOXi2550:pvr:rvnFUJITSUSIEMENS:rnF44:rvr00030D005503B103:cvnFUJITSUSIEMENS:ct10:cvr: dmi.product.name: AMILO Xi 2550 dmi.sys.vendor: FUJITSU SIEMENS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1364148/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
