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 0000:05:00.0: 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. ** Attachment added: "crash when docking" https://bugs.launchpad.net/gnome-shell/+bug/1970495/+attachment/5673744/+files/wrong -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970495 Title: Window manager freezes when plugging in USB-C dock with external monitor ([drm] *ERROR* mstb 00000000f21f0a30 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. Problem DOES appear on Lenovo T470s (Intel). 2. Problem DOES appear on Lenovo T14 Gen2 (AMD). 3. Problem does NOT appear on either of the above *when in the Live Installer*. I specifically checked that my dock behaved well under the Live Installer before deciding to move my workstations to Jammy. Upon logging into a fresh Jammy install, I found the following problem behavior: When the dock is plugged in, the built-in display freezes and the dock-attached displays power up but never render anything (ie, they stay black). Unplugging the USB-C cable gets mouse/keyboard response back on the built-in display.
