Black screen out of nowhere

Asked by Maik Stappers

Hi everyone,
I'm using Ubuntu 12.10 on my Dell Laptop with an I7-3720QM Processor with an integrated intel HD 4000 video and an dedicated Nvidia NVS 5200M video card. I'm using Bumblebee to use the Nvidia Optimus feature.
From Time to time my screens turns Black and i can only see a Curser blinking in the upper Left corner of the screen and the Mousecurser.

I'm unable to enter anything in this "state". The only way to get my Computer back to work is to restart it.

I hope you can help me.
Greetings Maik

I recommend you report a bug. Optimus is a mess and best avoided. I expect you will get issues for a long while to come.

Can you help with this problem?
