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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1816860 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/xorg-server/+bug/1816860/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
