    blank screen after booting Kubuntu 14.04

    Hi everybody, :-)
    I have a blank screen after booting Kubuntu 14.04, after having it installed very recently. I've been searching in the Internet and only found solutions which change the modeset of the grub. This works. I no longer have blank screen BUT I can no longer hibernate, which is for me very important. Please would you have a suggestion ? :-)
    Mountain Man (from https://www.kubuntuforums.net/showthread.php?t=70551) wrote he just needed to downgrade to the version 2358.16 of the driver recommended for XCOM, how does he do that please?

    I have an NVIDIA.

    I have an NVidia GT 650M chip and I installed the following files and rebooted:

    My NVidia chip, which I cannot select as a primary GPU in the BIOS, behaves like it is the primary GPU. The desktop and every app runs on it.
