I love Linux Ubuntu but I am very ignorant to how it fails and about hardware. Could you please look at this jpeg and tell me how to proceed:
Is it a hardware or a software problem. It's a Dell Latitude Laptop e7450. The problem started with Ubuntu 18.04, so I changed to 20.04 hoping it would go away, but it didn't. The problem would go away if I rebooted, but now it is more frequent. Once it starts, the computer is frozen and the icons on the side bar become gray squares
