Status in gnome-shell package in Ubuntu: Incomplete Status in mutter package in Ubuntu: Incomplete 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.
