Hardware: Lenovo ThinkPad model 20ST0055AU
Description: Ubuntu 22.04.2 LTS
Release: 22.04
Kernel: 6.2.0-26-generic #26~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Jul 13 16:27:29 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
What I expected to happen:
Using Lenovo dock via Thunderbolt connector, and with two DisplayPort monitors connected for three monitors in total. Display should be usable, and in fact _does_ work with 5.19.
What happened instead:
When attempting to use any ubuntu kernel > 5.19 I have had garbled output on the DisplayPort monitors.
I've attached a picture taken with my phone on bootup while prompted for the disk encryption password.
The GUI also displays in a similar garbled fashion if I let it boot further and is unusable.
Unfortunately I don't have the dock details at the moment, but it's a Lenovo thunderport dock of some sort. I will obtain the details tomorrow and update this bug report then. |

When attempting to use any ubuntu kernel > 5.19 I have had garbled output on the DisplayPort monitors.
I've checked on a few 6.2.0 kernels as have come through as part of linux-image-generic-hwe-22.04-edge, plus it also occurs on linux-image-6.1.0-1017-oem .
I've attached a picture taken with my phone on bootup while prompted for the disk encryption password.
The GUI also displays in a similar garbled fashion if I let it boot further and is unusable.
This happens on a Lenovo thunderbolt dock (which was actively attached when producing the lspci and lsusb output attached here), but I've also confirmed this issue occurs on a Dell WD19TB thunderbolt dock as well. |
