The X window system (commonly X Window System or X11, based on its current major version being 11) is a computer software system and network protocol that provides a basis for graphical user interfaces (GUIs) and rich input device capability for networked computers. It creates a hardware abstraction layer where software is written to use a generalized set of commands, allowing for device independence and reuse of programs on any computer that implements X.
X windows is a reliable system for remote graphical user interfaces that allows many people to share the processing power of a time-sharing computer and to collaborate with each other through client applications running on remote computers. The article will show in brief the steps necessary to reconfigure X in a debian/ubuntu system.
Open a terminal an type the following:
sudo apt-get purge nvidia*
Remove your xorg.conf
sudo rm /etc/X11/xorg.conf
Reinstall xorg completely
sudo apt-get install –reinstall xserver-xorg-core libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 libgl1-mesa-glx:amd64 libgl1-mesa-dri:amd64
sudo dpkg-reconfigure xserver-xorg
sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current
Reboot the system after completing the reconfiguration of the x server
