** Description changed: I am using a docking station for my laptop. After install the 4.15.0-44 update my external monitors goes undetected after logging in or having the laptop closed. I am on 18.04.1 LTS with Intel® HD Graphics 620 (Kaby Lake GT2) Graphics. Going back to the 4.15.0-43 version makes it all work fine again. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.5 + Architecture: amd64 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: jonas 2407 F.... pulseaudio + CurrentDesktop: ubuntu:GNOME + DistroRelease: Ubuntu 18.04 + HibernationDevice: RESUME=UUID=80397b76-2ded-4f7d-adbf-dfdface8e2d4 + InstallationDate: Installed on 2018-10-17 (103 days ago) + InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) + MachineType: LENOVO 20HF004MMX + Package: linux (not installed) + ProcFB: 0 inteldrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.15.0-44-generic root=UUID=64cf1582-d574-4e2f-a40a-7942c40caf5d ro quiet splash vt.handoff=1 + ProcVersionSignature: Ubuntu 4.15.0-44.47-generic 4.15.18 + RelatedPackageVersions: + linux-restricted-modules-4.15.0-44-generic N/A + linux-backports-modules-4.15.0-44-generic N/A + linux-firmware 1.173.3 + Tags: bionic + Uname: Linux 4.15.0-44-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dip docker kvm lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 09/14/2018 + dmi.bios.vendor: LENOVO + dmi.bios.version: N1WET51W (1.30 ) + dmi.board.asset.tag: Not Available + dmi.board.name: 20HF004MMX + dmi.board.vendor: LENOVO + dmi.board.version: SDK0J40697 WIN + dmi.chassis.asset.tag: No Asset Information + dmi.chassis.type: 10 + dmi.chassis.vendor: LENOVO + dmi.chassis.version: None + dmi.modalias: dmi:bvnLENOVO:bvrN1WET51W(1.30):bd09/14/2018:svnLENOVO:pn20HF004MMX:pvrThinkPadT470s:rvnLENOVO:rn20HF004MMX:rvrSDK0J40697WIN:cvnLENOVO:ct10:cvrNone: + dmi.product.family: ThinkPad T470s + dmi.product.name: 20HF004MMX + dmi.product.version: ThinkPad T470s + dmi.sys.vendor: LENOVO ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1813663/+attachment/5233565/+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/1813663 Title: External monitors does not work anymore 4.15.0-44 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813663/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
