Comment 10 for bug 116382

I did what you said in the post, using "sudo apt-get remove nvidia-glx-legacy", and "sudo apt-get install nvidia-glx". This worked. However, there was no "/lib/linux-restricted-modules/.nvidia_legacy_installed" file. (I only remembered this step after rebooting, though...) I can run my games, and the glxgears!

Attached are the results of glxinfo and glxgears. Also, while glxgears was running, I saw a picture of some gears rotating. (I assume that's normal! :D)

Attached are my:
/etc/X11/xorg.conf
/var/log/Xorg.0.log
