Hello croaker.
Could you give details of your machine?
I've seen that in Ubuntu 13.04 there are many problems with notebooks with Intel CPU and nVidia graphics card. I suspect that this problem also may be related to desktop computers that have Intel processor with iGPU and of multi-GPU or multi-monitor features. My computer is an Intel i7-3770 on an Asus P8Z77-V LX.
