I am desperate to solve this problem… I have been running Ubuntu 13.04![enter image description here] for a month on a Lenovo Y410P computer, there has been many problems but nothing too critical. But then last night, whenever I have my computer to "suspend", it directly goes to a black screen with a non-moving white cursor at the upper left corner. The forum said "You need at least 10 reputation to post images" so I can't post images for you to see.
Then NOTHING works except for the power button. I tried to press all possible combination of keys but, really, nothing works.
This is different from going to suspend but wake up black screen--it DOES NOT go to suspend at all! The computer is always running.
Thank you SO MUCH for your help in advance! The lenovo people said "We only help Windows".
