Comment 20 for bug 1432843

Tested a Lubuntu 15.05 32bit image in development and noticed, my monitor would go blank during the display of the Lubuntu splash image. Rebooted the image, and just as the splash screen appeared, pressed ctrl+esc which makes Lubuntu output the boot activities. As it when down the list of services it was activating, all the text on the screen started disappearing and reappearing. Pressed ctrl+alt+f4, was brought to a tty terminal. Logged in and typed "startx". The Xserver started yet all that appeared was an error message window and a notification. The rest of the screen was black.
