Screen goes wonky when HDMI device is plugged in

[Jeff Lane ]

On plugging in HDMI devices, the screen is scrambled. Pretty simple.

Boot and log in.
Plug in HDMI device
Watch the screen scramble

This occurs with the Radeon driver.

I managed to recover the system the first time by unplugging the device, however, on the second attempt, the screen scrambled and stuck that way and I had to reboot to recover the desktop.

The device in question is an HDMI audio device that provides audio out and VGA port for an HDMI connection. Check with ctf to see the device
