Found a fix for my problem and it now working. Overview of my problem: Ubuntu 12.10 + NVIDIA GeForce 9300 GS Unity do not start Ubuntu 12.10 + Compiz (opengl) - Fatal: glXQueryExtensionsString is NULL for screen 0
What I did to solve this issue: re-installed the nvidia drivers following this tutorial: http://www.dedoimedo.com/computers/ubuntu-quetzal-nvidia.html sudo apt-get install build-essential linux-source uname-r sudo apt-get install linux-headers-`uname -r` sudo apt-get install nvidia-current sudo /sbin/lsmod | grep nvidia no nvidia found, so: sudo depmod -a sudo modprobe nvidia_current sudo /sbin/lsmod | grep nvidia now it is ok, with count 0 sudo /etc/init.d/lightdm restart unity is restored! yay! Hope this helps someone.
