Public bug reported: In 13.10 and previous releases, locking the screen would go to the login screen, and then blank the screen and put the display to sleep. In 14.04, it goes to the login screen, then fades to black, but after that the screen is replaced with what looks like a corrupted texture buffer of the login screen, with alternating black and corrupted chunks in the framebuffer, and then the screen never goes to sleep, it just stays like that.
I can't adequately capture a screenshot since, of course, it's at the login screen. Hopefully this is replicable on other systems using the NVidia 331 binary drivers.
