So, the computer suspends just fine. When I try to wake it up, the screen flickers a bit, and then there's a black screen with all kinds of awful colored lines all over it. The mouse works normally, but it seems to be the only thing that functions. The only way to fix it seems to be doing a hard power off.
My graphics card is Nvidia, but that's all I really know about it.
My computer is a HP Pavillion dv9000.
