I'm trying to get CUDA running on my Dell Precision M6700 laptop. I use Ubuntu 12.04 for the moment but I can switch to a newer version if it facilitates the installation of CUDA.
I just want CUDA to run, I don't really care about power management.
After some reading I decided to install bumblebee because my laptop uses Optimus, I followed the instructions here : https://wiki.ubuntu.com/Bumblebee I also updated the drivers to nvidia-319 driver.
Now I am unable to boot my computer with graphics; I end up with a frozen prompt. I still have access to the terminal prompt in recovery mode but I don't know where to look for errors.
I tried things like apt-get remove --purge nvidia* etc. How can I get the graphic mode working again to try something else ?
