** Description changed: Suspend doesn't work when closing the lid on my ThinkPad T420s. There is no issue with 14.10 or 14.04. Kernel 4.0 do not help. dmesg when closing/opening with kernel "Linux alex-ThinkPad-T420s 3.19.0-7-generic #7-Ubuntu SMP Thu Feb 26 20:19:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux": [ 94.842668] systemd-logind[1262]: Lid closed. [ 102.468204] systemd-logind[1262]: Lid opened. [ 102.468661] i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment [ 124.075694] systemd-logind[1262]: Removed session c1. The i915 seems to be unrelated: it appears after the lid is opened again, and "pci=noacpi" makes it disappear but the bug stays. I managed to got it to work, after playing with the e1000e driver as suggested on https://bbs.archlinux.org/viewtopic.php?pid=1414261#p1414261, but with a dubious and inconsistent state: - doing nothing, e1000e loaded, it never goes to suspend when I close the lid (tried 5 times) - removing e1000e, goes to suspend when I close the lid - doing nothing, e1000e removed, it again cannot go to suspend when I close the lid - loading e1000e, goes to suspend when I close the lid WORKAROUND: Manually suspend. + --- + ApportVersion: 2.16.2-0ubuntu1 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: alex 1914 F.... pulseaudio + CurrentDesktop: Unity + DistroRelease: Ubuntu 15.04 + InstallationDate: Installed on 2015-03-07 (0 days ago) + InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) + MachineType: LENOVO 4171CTO + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.19.0-7-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7 + ProcVersionSignature: Ubuntu 3.19.0-7.7-generic 3.19.0 + Tags: vivid + Uname: Linux 3.19.0-7-generic x86_64 + UpgradeStatus: Upgraded to vivid on 2015-03-07 (0 days ago) + UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 07/18/2013 + dmi.bios.vendor: LENOVO + dmi.bios.version: 8CET58WW (1.38 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 4171CTO + 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:bvr8CET58WW(1.38):bd07/18/2013:svnLENOVO:pn4171CTO:pvrThinkPadT420s:rvnLENOVO:rn4171CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: + dmi.product.name: 4171CTO + dmi.product.version: ThinkPad T420s + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1429489/+attachment/4337854/+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/1429489 Title: Suspend not working when closing lid on ThinkPad T420s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1429489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
