[Bug 1817367] Re: Second display does not show up on dock of Lenovo Helix 2
Strange. Was I the only one? Whatever, just for completeness: All the same, but upgraded to 20_04 it works like a charm!

[Bug 1817367] Re: Second display does not show up on dock of Lenovo Helix 2
Okay, one small step further: I checked in the BIOS, and it offers the following three as primary displays: ThinkPad LCD Digital on ThinkPad Display on Dock Previously I used to see udippel@Uwe-ThinkPad-Helix-2nd:~$ grep . /sys/class/drm/*/enabled /sys/class/drm/card0-eDP-1/enabled:enabled /sys/class/drm/card0-HDMI-A-1/enabled:disabled /sys/class/drm/card0-HDMI-A-2/enabled:disabled udippel@Uwe-ThinkPad-Helix-2nd:~$ grep . /sys/class/drm/*/status /sys/class/drm/card0-eDP-1/status:connected /sys/class/drm/card0-HDMI-A-1/status:disconnected /sys/class/drm/card0-HDMI-A-2/status:disconnected udippel@Uwe-ThinkPad-Helix-2nd:~$ grep . /sys/class/drm/*/dpms /sys/class/drm/card0-eDP-1/dpms:On /sys/class/drm/card0-HDMI-A-1/dpms:Off /sys/class/drm/card0-HDMI-A-2/dpms:Off Then I attached a cable from the micro-HDMI-port on the side of the ThinkPad to the monitor. Quite following the obvious logic, what I get is udippel@Uwe-ThinkPad-Helix-2nd:~$ grep . /sys/class/drm/*/enabled /sys/class/drm/card0-eDP-1/enabled:enabled /sys/class/drm/card0-HDMI-A-1/enabled:enabled /sys/class/drm/card0-HDMI-A-2/enabled:disabled udippel@Uwe-ThinkPad-Helix-2nd:~$ grep . /sys/class/drm/*/status /sys/class/drm/card0-eDP-1/status:connected /sys/class/drm/card0-HDMI-A-1/status:connected /sys/class/drm/card0-HDMI-A-2/status:disconnected udippel@Uwe-ThinkPad-Helix-2nd:~$ grep . /sys/class/drm/*/dpms /sys/class/drm/card0-eDP-1/dpms:On /sys/class/drm/card0-HDMI-A-1/dpms:On /sys/class/drm/card0-HDMI-A-2/dpms:Off So the 'Digital on ThinkPad' seems to be the connector on the side of the tablet. It checks. Logically the third entry, HDMI-A-2 will be the Display on Dock. And there it looks like whatever display, it cannot be detected as 'connected'. xrandr follows the same logic: Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 256mm x 144mm 1920x1080 59.99 + 59.97* 59.9659.93 1680x1050 59.9559.88 1600x1024 60.17 1400x1050 59.98 1600x900 59.9959.9459.9559.82 1280x1024 60.02 1440x900 59.89 1400x900 59.9659.88 1280x960 60.00 1440x810 60.0059.97 1368x768 59.8859.85 1360x768 59.8059.96 1280x800 59.9959.9759.8159.91 1152x864 60.00 1280x720 60.0059.9959.8659.74 1024x768 60.0460.00 960x720 60.00 928x696 60.05
[Bug 1817367] Re: Second display does not show up on dock of Lenovo Helix 2
I tried another cable, even a proper Samsung monitor (contrary to the digital TV as before). Nothing at all. In W10 the lenovo diagnostics does correctly receive and handle the EDID-data. I tried all other dock functionalities, like Ethernet, headphone. All work properly under *nix out of the box. (Actually I had bought that dock because it doesn't need drivers, lenovo doesn't offer any. It connects to the dock connector on the tablet instead of through USB 3.0 like all other docks). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1817367 Title: Second display does not show up on dock of Lenovo Helix 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1817367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1817367] Re: Second display does not show up on dock of Lenovo Helix 2
apport information ** Tags added: apport-collected bionic ** Description changed: With reference to 1816860. My dual-boot recognizes and switches to the second monitor under W10, it seems that kubuntu 18.04 does not recognize that monitor, and does not offer to use it. The results of xrandr and some in /sys/class/drm can be found in that report, where it was suggested to file a bug here for the part of it that it doesn't see any second monitor. I ran ubuntu-bug gdm3, but it didn't show anything here. It only shows 'Already logged in'. I'll try again once I know the number of this bug here. I'll be happy to help as far as I can to get my setup running. + --- + ProblemType: Bug + ApportVersion: 2.20.9-0ubuntu7.5 + Architecture: amd64 + AudioDevicesInUse: + USERPID ACCESS COMMAND + /dev/snd/controlC2: udippel1551 F pulseaudio + /dev/snd/controlC1: udippel1551 F pulseaudio + /dev/snd/controlC0: udippel1551 F pulseaudio + CurrentDesktop: KDE + DistroRelease: Ubuntu 18.04 + HibernationDevice: RESUME=UUID=73792941-18ec-4d73-9640-1844bdad05dc + InstallationDate: Installed on 2019-02-16 (6 days ago) + InstallationMedia: Kubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) + MachineType: LENOVO 20CHS10P02 + Package: linux (not installed) + ProcFB: 0 inteldrmfb + 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 + RelatedPackageVersions: + linux-restricted-modules-4.15.0-45-generic N/A + linux-backports-modules-4.15.0-45-generic N/A + linux-firmware 1.173.3 + Tags: bionic + 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 ** Attachment added: "AlsaInfo.txt" https://bugs.launchpad.net/bugs/1817367/+attachment/5241015/+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/1817367 Title: Second display does not show up on dock of Lenovo Helix 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1817367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
