I get a freeze during boot that I think is caused by this:
30.813] (EE) NVIDIA(GPU-0): The NVIDIA kernel module does not appear to be receiving
30.813] (EE) NVIDIA(GPU-0): interrupts generated by the NVIDIA GPU at PCI:2:0:0.
30.813] (EE) NVIDIA(GPU-0): Please see Chapter 8: Common Problems in the README for
30.813] (EE) NVIDIA(GPU-0): additional information.
The freeze gives me a blank screen with cursor but completely unresponsive to anything other than hard reboot.
Delete all nvidia-driver-pacckages from Repo, disable the Repo, download the latest nvidia-driver from here: http://download.nvidia.com/XFree86/Linux-x86_64/
make the driver executable (chmod +x), boot to Runlevel 3 (multiuser.target) and install the downloaded driver.
