My 12.04 x64 system won't boot into GUI, but I can still use virtual console with my own account, so apparently it's the Windows Management System that's causing it, how can I reinstall it from tty, what's the
Please refer to ServerGUI.
The answer is to use this commands in terminal:
sudo apt-get install xorg openbox
X11 Client Installation
To do this, install the xauth pachage, then install the applications you need, and apt-get will bring in other packages as needed to satisfy the dependencies.
sudo apt-get install xauth
X11 Server Installation
To install a minimal X11 on Ubuntu Server Edition enter the following:
sudo apt-get install xorg sudo apt-get install openbox
If you certainly have run into this problem , type in the following commands:
sudo apt-get update sudo apt-get upgrade sudo apt-get install fxlrg sudo apt-get install xserver-xorg-core sudo apt-get install xserver-xorg sudo apt-get install xorg sudo apt-get install xorg openbox sudo apt-get install ubuntu-desktop
and you are good to go. The statements from top to bottom are dependencies to the statements after them.
