Public bug reported:
I have a Thinkpad T520 which I use frequently both undocked and docked
with dual monitors. It all works fine when it is first powered on in
either configuration, as well as when it awakes from sleep. However,
once I switch to the opposite configuration from the initial power-up, I
experience brief moments of unresponsiveness. I switch between
configurations by entering suspend (sleep), either docking or undocking
the laptop, and then returning from suspend mode.
The unresponsiveness is most often triggered by tooltips appearing in
any program, and the system remains unresponsive until the tooltip
disappears. The behavior may occur for other types of windows or UI
components, but I can't say for certain. When I'm experiencing this
issue, the mouse moves and most screen updates still happen (It will
cause most video playback to pause, however). However, mouse clicks and
typing are ignored or queued up.
I'm using Ubuntu 15.04, with the nvidia-355 binary driver. I've used
other versions of the nvidia driver, and they have all exhibited this
behavior or had other issues. I don't recall having this issue with
14.10, but I can't confirm it.
