Public bug reported:
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.
