apport information ** Tags added: apport-collected precise running-unity
** Description changed: I did the kernel smoke test for the quantal kernel on precise. I can suspend and resume however when I resume I the screen stays black. It looks like the backlight isn't coming on, but it's noteable that I don't see anything on my external screen either. I can see consoles on my external monitor (over HDMI) and if I disconnect the HDMI cable and reconnect it then I am also able to see my Unity session on that screen. This issue is present with both the quantal kernel and the stock 12.04 one. My setup is a Lenovo Thinkpad E525, AMD A8-3500m. + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.25. + ApportVersion: 2.0.1-0ubuntu12 + Architecture: amd64 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 1: Generic_1 [HD-Audio Generic], device 0: CONEXANT Analog [CONEXANT Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC1: tealeg 2861 F.... pulseaudio + /dev/snd/controlC0: tealeg 2861 F.... pulseaudio + Card0.Amixer.info: + Card hw:0 'Generic'/'HD-Audio Generic at 0xf0b44000 irq 48' + Mixer name : 'ATI R6xx HDMI' + Components : 'HDA:1002aa01,00aa0100,00100200' + Controls : 6 + Simple ctrls : 1 + Card0.Amixer.values: + Simple mixer control 'IEC958',0 + Capabilities: pswitch pswitch-joined penum + Playback channels: Mono + Mono: Playback [on] + Card1.Amixer.info: + Card hw:1 'Generic_1'/'HD-Audio Generic at 0xf0b40000 irq 16' + Mixer name : 'Conexant CX20590' + Components : 'HDA:14f1506e,17aa21ea,00100002' + Controls : 18 + Simple ctrls : 10 + Card29.Amixer.info: + Card hw:29 'ThinkPadEC'/'ThinkPad Console Audio Control at EC reg 0x30, fw unknown' + Mixer name : 'ThinkPad EC (unknown)' + Components : '' + Controls : 1 + Simple ctrls : 1 + Card29.Amixer.values: + Simple mixer control 'Console',0 + Capabilities: pswitch pswitch-joined penum + Playback channels: Mono + Mono: Playback [on] + DistroRelease: Ubuntu 12.04 + HibernationDevice: + # RESUME=/dev/sda5 + RESUME='UUID=61453936-e394-41de-8b00-5ee8f17023b3' + InstallationMedia: Ubuntu-Server 12.04 LTS "Precise Pangolin" - Alpha amd64 (20111129) + MachineType: LENOVO 12002KG + Package: linux 3.2.0.27.29 + PackageArchitecture: amd64 + ProcEnviron: + LANGUAGE=en_GB:en + TERM=xterm + PATH=(custom, user) + LANG=en_GB.UTF-8 + SHELL=/bin/bash + ProcFB: 0 radeondrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.5.0-7-generic root=UUID=c2742c1e-158f-446d-9884-d6f037d7fa8c ro quiet splash elevator=deadline + ProcVersionSignature: Ubuntu 3.5.0-7.7~precise1-generic 3.5.0 + RelatedPackageVersions: + linux-restricted-modules-3.5.0-7-generic N/A + linux-backports-modules-3.5.0-7-generic N/A + linux-firmware 1.79 + Tags: precise running-unity + Uname: Linux 3.5.0-7-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip kvm libvirtd lpadmin plugdev sambashare sudo + WifiSyslog: + + dmi.bios.date: 07/28/2011 + dmi.bios.vendor: LENOVO + dmi.bios.version: 8IET34WW(1.07) + dmi.board.asset.tag: Not Available + dmi.board.name: 12002KG + dmi.board.vendor: LENOVO + dmi.board.version: Not Available + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: Not Available + dmi.modalias: dmi:bvnLENOVO:bvr8IET34WW(1.07):bd07/28/2011:svnLENOVO:pn12002KG:pvrThinkPadE525:rvnLENOVO:rn12002KG:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: + dmi.product.name: 12002KG + dmi.product.version: ThinkPad E525 + dmi.sys.vendor: LENOVO ** Attachment added: "AcpiTables.txt" https://bugs.launchpad.net/bugs/1034002/+attachment/3252205/+files/AcpiTables.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1034002 Title: Lenovo E525 screen black on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1034002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
