On my Acer Travelmate laptop, the Synaptics touchpad does not work under either the live environment, or after installation (after all updates had been applied, which brought the kernel to version 5.3.0-26-generic). The touchscreen operated normally in both, so mouse control was still possible, but obviously it would be nice if the touchpad could operate correctly too.
The work-around mentioned in comment #43 of LP: #1854798 caused the touchpad to operate normally, so this might at least be related to that issue.
