Please also try *installing* xserver-xorg-input-synaptics and tell us if that allows Xorg sessions to work.

PopOS 20.04 fully updated. I have experienced this bug on stock Ubuntu 20.04 as well as Kubuntu 20.04. When at the login page, the trackpad and keyboard operate as they should. Once the login process is complete and the desktop is displayed, the keyboard still works as expected but the trackpad no longer controls the pointer. The touch display still functions as expected but the trackpad on the keyboard dock doesn't work. The attached document is my device list, here is the evtest: Input driver version is 1.0.1 Input device ID: bus 0x3 vendor 0x6cb product 0x2819 version 0x111 Input device name: "Synaptics T Pad V 01.31 Touchpad" Supported events: Event type 0 (EV_SYN) Event type 1 (EV_KEY) Event code 272 (BTN_LEFT) Event code 325 (BTN_TOOL_FINGER) Event code 330 (BTN_TOUCH) Event code 333 (BTN_TOOL_DOUBLETAP) Event code 334 (BTN_TOOL_TRIPLETAP) Event type 3 (EV_ABS) Event code 0 (ABS_X) Value 483 Min 0 Max 1056 Resolution 12 Event code 1 (ABS_Y) Value 266 Min 0 Max 516 Resolution 12 Event code 47 (ABS_MT_SLOT) Value 0 Min 0 Max 2 Event code 53 (ABS_MT_POSITION_X) Value 0 Min 0 Max 1056 Resolution 12 Event code 54 (ABS_MT_POSITION_Y) Value 0 Min 0 Max 516 Resolution 12 Event code 55 (ABS_MT_TOOL_TYPE) Value 0 Min 0 Max 2 Event code 57 (ABS_MT_TRACKING_ID) Value 0 Min 0 Max 65535 Event type 4 (EV_MSC) Event code 5 (MSC_TIMESTAMP) Properties: Property type 0 (INPUT_PROP_POINTER) Property type 2 (INPUT_PROP_BUTTONPAD) Testing ... (interrupt to exit) I did try to remove xserver-xorg-input-synaptics, but it is not installed on 20.04. There is still an issue with Wayland and the trackpad, but it's different than Xorg so the problem may be in how Xorg is processing the trackpad (I honestly don't know) - in Wayland, it will work until I attempt to run the sofware center.
