Public bug reported:
After resuming from a suspend, the Ubuntu UI lags so much the system is not
usable. However, this happens only if chrome is running (or is started if not
already running) and hardware acceleration is enabled in chrome.
I've tried both GNOME Shell and Unity with the same result. ssh into the host
works fine while the UI is unusable, showing excessive CPU usage by Xorg,
gnome-shell and chrome processes.
I tried disable the NVIDIA drivers to test with nouveau, but then the
screen will not turn on after resume.
