I am on lubuntu 19.10, old Imac with AMD® Rv730, kernel 5.3.0-29. Ever since upgrade to 19.10 I have issues with my keyboard (usb) and mouse (both usb and wireless). Certain keys are dead and certain key combinations stopped working. My mouse cursor just dissappears from time to time until I reboot. Before doing a fresh install I like to see what I can do to fi this.
