Public bug reported:
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.
