** Description changed: In HP Compaq 2510p laptop the FN-hotkeys for brightness control have no effect. FN+f9 is supposed to decrease brightness, but the brightness does not change. No message is displayed on screen. FN+f10 is supposed to increase brightness, but the brightness does not change. No message is displayed on screen. Brightness can be controlled from system settings / brightness and lock. Also brightness is changed during idle or power adapter plugged or unplugged. + Reverse mainline kernel version bisecting revealed: + kernel-bug-exists-upstream-v3.7-rc3-raring + kernel-fixed-upstream-v3.7-rc4-raring + ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: linux-image-3.5.0-17-generic 3.5.0-17.28 ProcVersionSignature: Ubuntu 3.5.0-17.28-generic 3.5.5 Uname: Linux 3.5.0-17-generic x86_64 ApportVersion: 2.6.1-0ubuntu6 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: leppis 2004 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: leppis 2004 F.... pulseaudio Date: Sun Nov 4 10:21:36 2012 HibernationDevice: RESUME=UUID=49ae27dd-896f-4082-9cd4-d8cb3b84a03b InstallationDate: Installed on 2012-10-10 (24 days ago) InstallationMedia: Ubuntu 12.04.1 LTS "Precise Pangolin" - Release amd64 (20120823.1) MachineType: Hewlett-Packard HP Compaq 2510p MarkForUpload: True PccardctlIdent: - Socket 0: - product info: "HP - ", "PC Card Smart Card Reader - ", "", "" - manfid: 0xffff, 0x0001 + Socket 0: + product info: "HP + ", "PC Card Smart Card Reader + ", "", "" + manfid: 0xffff, 0x0001 PccardctlStatus: - Socket 0: - 5.0V - 16-bit - PC Card - Subdevice 0 (function 0) [unbound] + Socket 0: + 5.0V + 16-bit + PC Card + Subdevice 0 (function 0) [unbound] ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.5.0-17-generic root=UUID=62599160-9cbb-4d52-bcc1-c301df6ead94 ro quiet splash vt.handoff=7 RelatedPackageVersions: - linux-restricted-modules-3.5.0-17-generic N/A - linux-backports-modules-3.5.0-17-generic N/A - linux-firmware 1.95 + linux-restricted-modules-3.5.0-17-generic N/A + linux-backports-modules-3.5.0-17-generic N/A + linux-firmware 1.95 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 07/06/2010 dmi.bios.vendor: Hewlett-Packard dmi.bios.version: 68MSP Ver.
