cuda 5.5, notebook with optmius and ubuntu 12.04

Hello.

I’m trying to setup my notebook with a 525m card but i’m having same problems.

I compiled the samples in the SDK and when I try to execute one that only uses cuda libraries, it work fine.

However, when I try to execute a sample that use opengl too (volumeRender), I got a message that there is no device. I even see the shape of the window, but it closes and the show the message.

Thank you.

You need to use bumblebee in order to run any of the CUDA samples that output to the display. See: https://wiki.ubuntu.com/Bumblebee

Hello,

Without optimus you have no warranty it will work. After installing the bumblebee you need to run the cuda programs with optirun ./cudaprogram.
