I have just installed KDE Plasma, and have no touchpad. Settings - Touchpad says, “No touchpad found” in a red box. At the moment, I have attached a USB mouse. How can I get the touchpad working please?
For information, my laptop is a new Acer Swift 3 (AMD Ryzen 5 4500U Radeon Graphics).
Thanks in advance.
UPDATE: Following a system reboot touchpad functionality appears OK.
