** Description changed:

- When I boot an Ubuntu 16.04 live DVD on a Gateway system with an AMD
- A6-5400K APU, with an integrated Radeon HD 7540D graphics adapter, I get
- a black screen with no video image.  If I boot the live CD with
- "nomodeset" added to the kernel parameters, the system boots and shows
- the desktop at low resolution.  If I look at "dmesg" output, I see these
- messages:
