#StackBounty: #multi-monitor #thinkpad #dock-station Lenovo Thinkpad Dockingstation Hybrid C-USB doesn't recognize external monitors

Bounty: 50

I’m running Debian Buster on my Thinkpad T480 (link to manufacturer)

$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 10 (buster)
Release:    10
Codename:   buster

I got from my office a Thinkpad docking station for my wokring computer, but would also like to use it for my Linux one (private computer). It is the following Docking station: Lenovo USB-C Hybrid Dock 135W.

I searched around and tried to disable secure boot in the Thunderbolt BIOS setup. However, it still doesn’t recognize my external monitors, nor USB devices. It gets charged at least. Does someone know how to make it run on Debian?

#StackBounty: #linux #graphics #multi-monitor #intel-graphics #dock-station Dual monitor issues Linux Mint Thinkpad Docking station

Bounty: 100

The setup

  • T460 thinkpad (Intel HD Graphics) docked with lid closed
    connected to two external monitors one via DVI and the other via HDMI

The problem

  • During boot, up until the login screen both monitors work fine. But as soon as I sign in the monitor connected with the DVI will go blank about %80 of the time.

My workaround solutions to fix this problem

  • Going back to the login screen via CTRL ALT BACKSPACE and signing in again will almost always fix it.
  • Physically removing/reinserting the cable will almost always fix it.

Behavior

  • When logging in and experiencing the problem the monitor seems to be recognized as I can move my mouse into its resolution, but the monitor claims it is waiting for signal.

When did the problem occur?

  • After moving and going from three to two monitors as well as reinstalling Linux Mint for luks encryption

I’m pretty green when it comes to diagnosing graphical problem. I would be happy to paste logs, but I’m not sure which ones would be helpful. Please let me know which logs might be worth taking a look at, or any other suggestions you may have!
