Error: on wake (lid opened) the display is moving pixels

Asked by Bruce MacAlister

When the laptop lid is opened, the screen is a set moving of moving squares of moving pixels. It began around 13 Jan 2020. I do software updates regularly so it may have started after such an update. I must re-boot to clear the problem. It otherwise runs well.

The system:
Dell Latitude-E6510
Ubuntu 18.04.3 LTS
Gnome 3.28.2

What diagnostic data collection tools are available? What should I do next?

You may want to update the BIOS.

Thanks. Ir's not good news because this is a Linux-only system. I'll do some research on doing the update with WINE. Using FreeDOS seems to have the risk of wiping out Linux.
