This is a successful docking attempt. I rebooted my laptop with the dock attached. At about 06:30:30, I decide to remove the dock, in order to try to replicate the behaviour. At 06:30:37 I'm plugging it in again. I have not redacted these logs, no obfuscation etc, so yeah, you can see all the slack.desktop etcetera messages. I hope someone can make something of this. I can't. I'm just seeing my desktop crash randomly and I don't know where it comes from.

Here are two full logs. One where things go wrong. I'm walking upstairs
at 06:15 and at 06:16:17, the first logs indicate that the dock is
connected ("usb 1-4: new high-speed USB device number 53 using
xhci_hcd"), the "Cypress Semiconductor USB Billboard" shows up 0.7
seconds later.
Please note that the "pci :05:00.0: BAR 13: no space for [io size
0x4000]" seem harmless, they also do occur on a successful docking
attempt.
At 06:16:22, Thunderbird starts complaining, "Couldn't map window ",
and 06:16:23 gnome-shell complains that an assertion about monitors
failed. I didn't check the source code.
Apparently, I'm impatient today, so I'm unplugging the dock again at
06:16:54, replugging it 06:17:04 because I saw a login screen i.e. my
session had crashed anyway and probably removing it again after a few
seconds. So all info after 06:17:14 or so should be regarded as "utter
mess, please ignore". I tried a few things afterwards, but basically
switching to tty2 and rebooted the system (at 06:20).
I'll add a successful docking attempt log file in the next comment.

Given the Bug Description says the problem doesn't occur in the live installer session, that suggests this is Wayland specific or even specific to atomic KMS.

My Thinkpad X1 gen 6 with Ubuntu 22.04, Lenovo 40AJ dock with 4K LG monitor with DP cable, will sometimes just show 2 or 4 lines with "DPCD read on addr 0x4b0 for 1 bytes NAKed", after which the system will just continue to work. But sometimes the "1 bytes NAKed" messages just keep running - which is when the session will crash, eventually. If I connect the dock with the laptop LCD on, the "1 bytes NAKed" will freeze the LCD. When I'm fast enough to disconnect the DP cable, the LCD unfreezes. However, reconnecting the DP will re-freeze the LCD. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1970495 Title: Window manager freezes when plugging in USB-C dock with external monitor ([drm] *ERROR* mstb f21f0a30 port 1: DPCD read on addr 0x4b0 for 1 bytes NAKed) Status in GNOME Shell: New Status in linux package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: 1.

I can reproduce this issue, too. When plug in the dock(with HDMI 4k monitor), the screen freeze and keyboard/touchpad won't work, but I still can ssh into the machine. Un-plug the dock, everything works again. BTW, I found gnome-shell runs in 100% while the issue happened, and un- plug the dock the CPU usage of gnome-shell comes back to normal. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1970495 Title: Window manager freezes when plugging in USB-C dock with external monitor ([drm] *ERROR* mstb f21f0a30 port 1: DPCD read on addr 0x4b0 for 1 bytes NAKed) Status in linux package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: 1.
