This question is a follow up on this one. I have recently upgraded from Ubuntu 12.04 to 14.04 and xserver broke during the process. I have tried reinstalling from the command line running the following:
sudo apt-get update sudo apt-get upgrade sudo apt-get -y install xserver-xorg sudo apt-get -y install x11-xserver-utils sudo apt-get install xorg openbox sudo apt-get install xserver-xorg-core sudo apt-get install xorg sudo apt-get install ubuntu-desktop
None of the above fixed x. I've also tried "upgrading" from a live DVD. I could not find an upgrade option, however. Most options implied erasing current partitions and one a side-by-side installation with previous ones. Now I'm thinking about restoring the xorg files from the live installation on the previous(already upgraded 14.04) installation. How should I approach this issue?
