Comment 56 for bug 813343

Could you please open a console do the following:

Start nvidia-settings, try to configure, then nvidia-settings freezes. Then go into your console an do (you can copy and paste the following):

cd ~/Desktop
mkdir reports
cd reports

sudo cp /var/log/lightdm/*
sudo apport-bug --save=~/Desktop/reports/apport.log nvidia-settings
sudo cp /etc/lightdm/lightdm.conf .
sudo cp /var/log/lightdm/*
sudo cp /etc/X11/xorg.conf .
sudo nvidia-bug-report.sh
sudo gunzip nvidia-bug-report.log.gz

sudo tar czvf reports.tgz *
sudo chmod 777 reports.tgz

And send the reports.tgz (it contains all necessary files).
