|What's particularly more important at this time is the log files

|Low was your driver installed before?  By hand?  By linux-restricted-|modules?
|By envy?  By automatix (shrug...)

I just had to downgrade my Nvidia drivers and had a similar problem with the "low graphics mode" popping up.  For me, the issue was adding nv and nvidia_new to the restricted drivers file along with removing /etc/init.d/nvidia-kernel



If you wish to install the NVIDIA Linux graphics driver on a Debian GNU/Linux or Ubuntu system that ships with Xorg 7.x, please ensure that your system meets the following requirements:

    * development tools like make and gcc are installed
    * the linux-headers package matching the installed Linux kernel is installed
    * the pkg-config and xserver-xorg-dev packages are installed
    * the nvidia-glx package has been uninstalled with the --purge option and the files /etc/init.d/nvidia-glx and /etc/init.d/nvidia-kernel do not exist

If you use Ubuntu, please also ensure that the linux-restricted-modules or linux-restricted-modules-common packages have been uninstalled. Alternatively, you can edit the /etc/default/linux-restricted-modules or /etc/default/linux-restricted-modules-common configuration file and disable the NVIDIA linux-restricted kernel modules (nvidia, nvidia_legacy) via:

    DISABLED_MODULES="nv nvidia_new"

Additionally, delete the following file if it exists:
