After I update my Raspberry Pi 3 software to the latest version using apt-get update, then apt-get upgrade, everything stops responding in the Pixel Desktop. Keyboard, mouse and wi-fi ALL stop working. I've been avoiding the updates for months, since this has been a persistent problem. Every time I do the update, I end up reinstalling the OS from the image and keeping it un-updated. Luckily I have installed RetroPie with the OS, which forces it to tty1, where I CAN use my keyboard. Though wi-fi still doesn't work (plugging in a network cable allows the network to work). I've even updated the firmware, just in case that was the issue. It's still a no go. Am I the only one experiencing this issue?
