On Ubuntu 19.10, my cursor freezes after a long period of time not using the system. The keyboard works fine then, though.
My laptop is a 2011 MacBookPro, where I'm only using the Intel videocard, as the Radeon card is defective. I boot 19.10 normally, and 19.10 runs very stable on this machine, unlike Elementary OS even when bypassing the Radeon video card.
