The three sets of three are: the first three on dock after start, the next three off the dock and the last three after reinsertion. It looks like no detection of any change with respect to display.
The machine is a Helix 2, Machine Type Model: 20CHS10P02 (details can be found on lenovo support website, if needed). It has a micro-HDMI-output on the tablet, but also offers video via a USB-2-video adapter (that I do not have, otherwise I could test it). The dock is 4X10H04503, details under https://support.lenovo.com/de/en/accessories/ACC100200. It has one HDMI-plug and also some USBs that are said to allow the use of the adapter as described above. The external monitor is a SONY Digital-TV BRAVIA, KDL-32CX525. If it helps, I can produce a Youtube-clip showing the behaviour. Maybe that helps? I also wonder, if it is possible one way or another to store the dmesg respectively the xorg log for those sessions that need abandoning due to only the mouse cursor being visible. Do you think those could help to identify what makes the boot-up process stop? Or do you think it goes through and simply doesn't send anything to the display? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1816860 Title: Second display does not show up on dock of Lenovo Helix 2 Status in xorg-server package in Ubuntu: Incomplete Bug description: To me a deal-breaker: I bought the Helix 2 as machine on the dock, and I also bought the one out of the three docks that doesn't need extra driver (so it says), the 4X10H04503. I stuck the tablet into it, with Windows, and the second display came up without any additional driver. With kubuntu 18.04 I can't make it appear. xrandr doesn't show it. Now I wonder, where else it might pop up? I mean, the dock works, I ran a unified Logitech receiver on it, and from the first second mouse and keyboard are available to my *buntu installation, of course the grub menu. I am quite disheartened, since I don't feel like going back to Windows after some 20 years on *nix. I am willing to help out as much as my very limited abilities allow me to. I can't believe that a dock which actually supplies power and keyboard and mouse data does not supply any information about the second monitor? --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.5 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CompositorRunning: None CurrentDesktop: KDE DistUpgraded: Fresh install DistroCodename: bionic DistroRelease: Ubuntu 18.04 DistroVariant: ubuntu ExtraDebuggingInterest: I just need to know a workaround GraphicsCard: Intel Corporation HD Graphics 5300 [8086:161e] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo HD Graphics 5300 [17aa:222b] InstallationDate: Installed on 2019-02-16 (4 days ago) InstallationMedia: Kubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) MachineType: LENOVO 20CHS10P02 Package: xorg-server (not installed) ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.15.0-45-generic root=UUID=0f5d3b8a-5cae-45cb-a42d-b89344359b2f ro quiet splash vt.handoff=1 ProcVersionSignature: Ubuntu 4.15.0-45.48-generic 4.15.18 Tags: bionic ubuntu Uname: Linux 4.15.0-45-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 10/31/2018 dmi.bios.vendor: LENOVO dmi.bios.version: N17ETA2W (2.02 ) dmi.board.asset.tag: Not Available dmi.board.name: 20CHS10P02 dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 11 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrN17ETA2W(2.02):bd10/31/2018:svnLENOVO:pn20CHS10P02:pvrThinkPadHelix2nd:rvnLENOVO:rn20CHS10P02:rvrSDK0E50510WIN:cvnLENOVO:ct11:cvrNone: dmi.product.family: ThinkPad Helix 2nd dmi.product.name: 20CHS10P02 dmi.product.version: ThinkPad Helix 2nd dmi.sys.vendor: LENOVO version.compiz: compiz N/A version.libdrm2: libdrm2 2.4.95-1~18.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 18.2.2-0ubuntu1~18.04.2 version.libgl1-mesa-glx: libgl1-mesa-glx 18.2.2-0ubuntu1~18.04.2 version.xserver-xorg-core: xserver-xorg-core 2:1.19.6-1ubuntu4.2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev N/A version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:18.0.1-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20171229-1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.15-2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1816860/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
