More precisely the login does not complete (in a reasonable time frame) and I cannot switch to another virtual terminal. Some menus can be selected, but there is no action (e.g. reboot) and I have to do a hard shutdown (pressing the power button for 4 sec.). The log files show a kernel oops. When attaching the dock after login the system seems to work normally. I do have the latest displaylink drivers installed (www.displaylink.com). Attached is a log file snippet. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.4 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2019-03-25 (483 days ago) InstallationMedia: Ubuntu 18.04.2 LTS "Bionic Beaver" - Release amd64 (20190210) Package: mutter 3.36.3-0ubuntu0.20.04.1 PackageArchitecture: amd64 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash ProcVersionSignature: Ubuntu 5.4.0-40.44-generic 5.4.44 Tags: focal Uname: Linux 5.4.0-40-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev remote sambashare sudo wireshark _MarkForUpload: True --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC2: leo 1928 F.... pulseaudio /dev/snd/controlC1: leo 1928 F.... pulseaudio /dev/snd/controlC0: leo 1928 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2019-03-25 (484 days ago) InstallationMedia: Ubuntu 18.04.2 LTS "Bionic Beaver" - Release amd64 (20190210) MachineType: LENOVO 20N8CTO1WW Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=de_DE.UTF-8 SHELL=/bin/bash ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/@focal/boot/vmlinuz-5.4.0-40-generic root=UUID=cbee37f5-8d6e-4d54-a71d-cd0f24de1427 ro rootflags=subvol=@focal quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.4.0-40.44-generic 5.4.44 RelatedPackageVersions: linux-restricted-modules-5.4.0-40-generic N/A linux-backports-modules-5.4.0-40-generic N/A linux-firmware 1.187.1 Tags: focal Uname: Linux 5.4.0-40-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev remote sambashare sudo wireshark _MarkForUpload: True dmi.bios.date: 06/15/2020 dmi.bios.vendor: LENOVO dmi.bios.version: R0YET44P (1.27 ) dmi.board.asset.tag: Not Available dmi.board.name: 20N8CTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0J40709 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrR0YET44P(1.27):bd06/15/2020:svnLENOVO:pn20N8CTO1WW:pvrThinkPadE490:rvnLENOVO:rn20N8CTO1WW:rvrSDK0J40709WIN:cvnLENOVO:ct10:cvrNone: dmi.product.family: ThinkPad E490 dmi.product.name: 20N8CTO1WW dmi.product.sku: LENOVO_MT_20N8_BU_SMB_FM_ThinkPad E490 dmi.product.version: ThinkPad E490 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887914/+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
