Comment 6 for bug 353502

I'm using 180.51 version of the nvidia driver. Installed by "sudo sh nvidia.run", I had the following error: "error: unable to open '/usr/lib/xorg/modules/extensions/libglx.so' for reading (no souch file or directory)", but the installation succesfully complete. Now the sistem doesn't freeze any more. It freeze only when i go to "system - preferences - screensaver".
