I have an HP Envy DV7 7212 with the GeForce GT 650M. I dual boot Windows 8 and Linux 12.10, Quantal. The video hardware operates properly under Windows 8. The Linux drivers are not loaded by the time that I try to login to X.

I get what looks like a safe X boot screen at 600x800 resolution

I've generated a great number of log files and reference some of their data here

nvidia-installer.log for the 313.18 installer shows no errors and successful completion

I've added blacklist entries in /etc/modprobe.d/blacklist.conf for nouveau and nvidiafb and my lsmod does not show them loaded. Though, the nvidia module is loaded with 0 users associated with it.

The system is running :

Linux TheTurk 3.7.0-030700-generic #201212102335 SMP Tue Dec 11 04:36:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

lsb_release produces the following output

Using the nvidia-debugdump tool to list graphics devices I receive the following output

lsmod provides a number of output items, however, the following are key

Having discovered that this could be an Optimus issue. I've installed Bumblebee according to their recommendations http://bumblebee-project.org/install.html#Ubuntu
However, I've ended up with some further issues. I'm searching for information on these, but I thought I'd go ahead and record them here for posterity.

First off, I get to the lightdm login screen just fine, but when I enter my password, I end up crashing the X server, or lightdm, and getting sent back to the login prompt, the login prompt reloads with that familiar chiming sound and further attempts to login result in the same crash and prompt repeating.

/var/log/upstart/bumblebee.log repeats the following 2 messages :

ls: cannot access /usr/lib/nvidia*/libGL.so: No such file or directory
/proc/self/fd/9 31: exec: /usr/sbin/bumblebeed: not found

the first message is odd because /usr/lib/nvidia-current/libGL.so does exist
the second is string because /usr/sbin/bumblebeed exists

/var/log/upstart/lightdm.log repeats this message :

** (process:12342): WARNING **: Error reading existing Xauthority: Error opening file: Permission denied Error writing X authority: Error

/var/log/syslog repeats this message :
