Bug Description
Gnome-shell sometimes hangs when i wake it from suspend (by opening the lid on my Dell E6520 laptop).
I open the lid, and it just shows the lock-screen background, and everything seems frozen. I am able to switch tty and move the mouse, but no upwards arrow animation (like there normally is when it is locked), and you cannot get to the password prompt.
This mostly happends when i open the lid of the laptop after having taken it out of a docking station. My normal procedure for taking it out of the docking station is:
1. When it is in the dock (using 2 external monitors, and laptop-lid closed) i lock Ubuntu with CTRL-ALT-L.
2. I undock the laptop.
3. I open the screen, and see that the screen turns on. After a few seconds i shut it again. As it is now undocked my power settings let it go into suspend nicely.
4. Later when i open the lid (might be hours later) it hangs like explained above.
I do this every day, and 1/4 times it has done this now. I don't think it is exclusively in this situation that i have experienced this bug, but this has now happened so many times this way, so it might have something to do with it ?
Tell me if you need further info, as i will gladly provide it.
