Yep, it's been something slightly short of a circus act : ) It does still occur, but not nearly as often as it used to. The new lock screen in 14.04 is much better than the one in 13.10 - I just tried locking the screen a dozen times in a row with no issue, and I've probably only seen the issue occur 2-3 times since I installed 14.04 (I blew away my old/other linux installs and fresh installed 14.04 the day it came out, looks like that was the 17th of April). I believe the times that it did re-occur, I had my screen locked overnight and when I came back to work in the morning, a terminal window in the second monitor had gone off screen (it was the only window on that screen). This actually happened to me this morning when I came in (May 30th, 2014).
The process I go through every night is: 1) lock the screen with Super + L, 2) turn off the monitors manually (push the physical power button). When I come in in the morning, I push the power buttons back on, and the lock screen is always there. I can then put in my password to unlock and get working. The first thing I usually run is 'sudo apt-get update' and 'sudo apt-get dist-upgrade' in a terminal to be sure I've got the latest packages and updates. In a potentially related issue, I can't reliably use the inactivity screen shutdown on my monitors - I have to set the 'System Settings'->'Brightness and Lock'->'Turn screen off when inactive for' to 'Never', otherwise my monitors will never come back once they've started sleeping (clicking or typing or running 'xset dpms force on' via ssh - I have to reboot the computer). I also have problems occasionally with my left monitor not coming on during a reboot - I sometimes have to power it off and power it on manually before the Ubuntu login screen will recognize it and drive the display. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

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. I expected the windows on the second screen to stay on the screen after unlocking the system. 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.
