Ubuntu 14.10, CUDA 7, installed throught deb repository and then sudo apt-get install cuda.

I have the Nvidia 349 drivers.

After reboot I'm stuck on a screen with written Ubuntu 14.10 and four points (three white, the last orange) on a black bar. If I press the shutdown button (once) it will shutdown after a few seconds.

I've seen this thread Blank screen after installing nvidia restricted driver but

  1. I don't have problems with the drivers themselves, only after installing cuda.
  2. I do not know how to open a console from that black screen.

To get a console press Ctrl+F1 at the broken login screen. If that does not work boot into recover mode, drop to a root prompt, remount the root directory :

mount -o rw,remount /

Once logged in try uninstalling cuda :

sudo apt-get remove cuda

or the driver 

sudo apt-get remove nvidia-349

or 

sudo apt-get remove nvidia-346

You are stuck at this login screen due to issue of Nvidia driver at startup. Try change to Intel at shutdown at set to Nvidia at startup.

  1. create select_intel.sh

    #!/bin/sh
echo <your ubuntu password> | sudo -S prime-select intel

  2. sudo +x select_intel.sh

  3. sudo mv select_intel.sh /etc/init.d/

  4. sudo ln -s /etc/init.d/select_intel.sh /etc/rc0.d/K99select_intel

  5. sudo ln -s /etc/init.d/select_intel.sh /etc/rc6.d/K99select_intel

For startup

  1. sudo nano /etc/rc.local

  2. add this code above exit 0

    echo <your ubuntu password> | sudo -S prime-select nvidia

Note that is your ubuntu password for sudo command. This is just a workaround, not a solution, but it works.
