It starts during the boot process. The display is normal from the Dell boot/startup screen through the grub screen to the Ubuntu logo screen and the password screens; in the instant that the top tool bar and left tool bar come on screen, the scan/diagonal artifact appears. The system was normal yesterday when I shut down and on boot-up this morning, it wasn't. I did run the Ubuntu software updater yesterday, and I didn't cycle power until shutdown last night.
