Terry Jones, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine 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. For example: kernel-fixed-upstream-v3.13-rc1 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. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing 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. ** This bug is no longer a duplicate of bug 765438 8086:2a42 [eMachines E527] On startup, the backlight is off on laptop ** No longer affects: linux (Ubuntu) ** Project changed: linux => linux (Ubuntu) ** Changed in: linux (Ubuntu) Remote watch: Linux Kernel Bug Tracker #42726 => None ** Tags removed: has-workaround ** Tags added: bios-outdated-v3.10 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.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/934707 Title: 8086:2a42 emachine e725 boots to valid display with no backlight Status in “linux” package in Ubuntu: Incomplete Bug description: Booting to a black screen, however a flashlight shows a faint login window. I can login, hear the startup sound, but still a black screen. Again a flashlight on the screen shows a faint desktop. I am assuming the backlight on the laptop is not responding. Pressing the function key and brightness adjustment keys does nothing. As a work around, adding the boot paramater acip_osi=Linux to Grub on startup allows me to have a screen, However, the function dim keys make it brighter while the function brighter keys make the screen dimmer. lsb_release -rd Description: Ubuntu precise (development branch) Release: 12.04 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+10ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-16.25-generic 3.2.6 Uname: Linux 3.2.0-16-generic x86_64 NonfreeKernelModules: wl .tmp.unity.support.test.0: ApportVersion: 1.91-0ubuntu1 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,dbus,mousepoll,regex,imgpng,gnomecompat,place,animation,session,move,resize,snap,vpswitch,winrules,grid,fade,workarounds,cube,expo,ezoom,scale,rotate,unityshell] CompositorRunning: compiz Date: Fri Feb 17 22:26:05 2012 DistUpgraded: Fresh install DistroCodename: precise DistroVariant: ubuntu DkmsStatus: bcmwl, 5.100.82.38+bdcom, 3.2.0-15-generic, x86_64: installed bcmwl, 5.100.82.38+bdcom, 3.2.0-16-generic, x86_64: installed ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device [1025:0212] Subsystem: Acer Incorporated [ALI] Device [1025:0212] InstallationMedia: Ubuntu 12.04 LTS "Precise Pangolin" - Alpha amd64 (20120119) MachineType: eMachines eMachines E725 ProcEnviron: PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.2.0-16-generic root=UUID=5dad1fe6-2c79-4412-ae39-0307a2f6db3e ro acpi_osi=Linux SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/16/2009 dmi.bios.vendor: eMachines dmi.bios.version: V3.04 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: eMachines E725 dmi.board.vendor: eMachines dmi.board.version: V3.04 dmi.chassis.type: 10 dmi.chassis.vendor: eMachines dmi.chassis.version: V3.04 dmi.modalias: dmi:bvneMachines:bvrV3.04:bd12/16/2009:svneMachines:pneMachinesE725:pvrV3.04:rvneMachines:rneMachinesE725:rvrV3.04:cvneMachines:ct10:cvrV3.04: dmi.product.name: eMachines E725 dmi.product.version: V3.04 dmi.sys.vendor: eMachines version.compiz: compiz 1:0.9.7.0~bzr2995-0ubuntu4 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.30-1ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 8.0~rc2-0ubuntu5 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 8.0~rc2-0ubuntu5 version.xserver-xorg-core: xserver-xorg-core 2:1.11.4-0ubuntu3 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.6.99.901+git20120126-0ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.14.99~git20111219.aacbd629-0ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.17.0-1ubuntu4 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20111201+b5534a1-1build2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/934707/+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
