[Chris Plummer <christopher.plummer@xxxxxxx>]

I just tried the AMD 64 Precise Pangolin 12.04.2 release using this file
- http://old-releases.ubuntu.com/releases/precise/ubuntu-12.04.2
-desktop-amd64.iso.  The screen locking works perfectly - I tried it
about 20 times in a row, and every time it's consistently good - the
screen immediately blanks with no flickers and a mouse movement brings
up the enter password dialog on the left-screen.  When I unlock, all the
windows are positioned as I left them before I locked the screen.

Trying this on 12.04 makes me realize just how bad the experience is on
13.10+; the screen lock is just plain broken.  It's very non-
deterministic in that it flickers or flashes often, sometimes one of the
screens shows what was on it before the lock, and most of the time the
enter password / unlock dialog shows up immediately without any mouse or
keyboard input.  This is in addition to the windows that I had open
disappearing offscreen.  I expect the consistent behavior of the 12.04
screen lock - both screens are blanked immediately with no flashes or
flickers and the unlock dialog only shows up after I move the mouse.

Title:
  Ubuntu 13.10 dual monitor screen lock causes windows to disappear off-
  screen

Status in “linux” package in Ubuntu:
  Incomplete

  I have a dual monitor set up with a Dell T5500 and an Nvidia Quadro
  NVS 295 graphics card.  I lock the screen with a window open on the
  second monitor, then unlock it again.  When the desktop shows again,
  the windows that were on the second screen are gone offscreen.  I
  expected them to still be on the second screen - I can workaround this
  by using Alt+Spacebar to move the window back.  This happens every
  time I lock the screen, and it happens if I use the Nouveau driver or
  if I use the proprietary driver.

  3) I expected the windows on the second screen to stay on the screen after unlocking the system.
  4) Instead, the windows disappeared off-screen - the Unity launcher still shows them being open, plus if I have multiple windows of an application open (i.e. the terminal), then double click the launcher icon, then it shows me all the windows and lets me choose one to bring forward, even the ones offscreen.  When I pick the offscreen one to bring forward, its icon just shoots offscreen again.
