I reinstalled the Nvidia-173 driver.
After that I removed it and rebooted.
When my PC restarted I got a message that my PC could start only in low graphics mode, and had only a terminal to logon, no desktop session.
I logged on and the output of lsmod is in the attached file lsmod3.txt where as you can see there are no graphics drivers (no nouveau a no Nvidia ones).
I ran a dpkg --list *nvidia* to find Nvidia drivers installed and as you can see in the attached nvidia.txt file, the Nvidia-173 drivers where still installed.
I had to remove them with dpkg -r and after reboot I found myself with the nouveau drivers installed.
This has happened to me quite often testing 12.10 kernel on 12.04.
