vik: 1) As per the sticker of the monitor itself (not from the Bug Description, or the result of a terminal command), could you please provide the full monitor manufacturer and model?
2) Regarding how you have the monitor connected, is it plugged into the dock's DVI-I, or DisplayPort port? If you switch the port is this still reproducible? 3) Regarding the connection of the monitor to the dock, is this via straight DVI-I cord, using dongle/adapter, etc.? 4) If you instead undock the computer, and plug the monitor directly into the computer, is this still reproducible? 5) Regarding the Lenovo ThinkPad OneLink Pro Dock, have you applied the latest firmware to it? ** Tags removed: latest-bios-1.29 ** Tags added: bios-outdated-1.38 regression-potential ** Attachment removed: "syslog.txt" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1578011/+attachment/4780928/+files/syslog.txt ** Changed in: xorg (Ubuntu) Importance: Medium => Low ** Changed in: xorg (Ubuntu) Status: Confirmed => Incomplete ** Summary changed: - Laptop sometimes doesn't detect external monitor when docked + [Lenovo ThinkPad Yoga Type 20C0] Laptop sometimes doesn't detect external monitor when docked into ThinkPad OneLink Pro Dock -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1578011 Title: [Lenovo ThinkPad Yoga Type 20C0] Laptop sometimes doesn't detect external monitor when docked into ThinkPad OneLink Pro Dock Status in xorg package in Ubuntu: Incomplete Bug description: Lenovo Thinkpad Yoga S1 sometimes doesn't detect external monitor when docked with a Onelink Pro dock.
