Public bug reported:
When I close the lid on my laptop to put Kubuntu to sleep, it wakes up
with a black screen - with the exception of a single blinking cursor (_)
in the upper left corner. Machine is clearly on. Turning off/back on
gets the machine back into a good state.
I had a prior installation of Kubuntu on this box and it did not have
this problem, though I do not remember if it had the nvidia drivers.
