I have a ASUS A55V on which I installed ubuntu 12.04 in dual boot with windows 8.
The pc has an integrated Intel HD Graphics and a Nvidia geforce 610m.
I then installed bumblebee on ubuntu, giving exactly these command, just after the OS installation
sudo apt-get purge nvidia-current sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee-nvidia
I rebooted, and everything seems to work quite fine.
Then I downloaded the CUDA 5.0 toolkit for Ubuntu 11.10, and I DON’T install the graphic card drivers, but only the toolkit and the samples.
In the end I could compile and execute the sample without problems, and all right.
So, I reboot the pc, I select ubuntu in the grub, the ubuntu loading screen appears for a moment and then suddenly goes to a black screen, and nothing happens anymore (I waited more than five minutes, but I can never get to the ubuntu login screen).
Any ideas on the origin of the problem?
