You need to remove the AMD driver. Run the following commands and restart the system:
sudo apt-get remove --purge fglrx* sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core xserver-xorg-video-intel sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup ** Changed in: xorg (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1196244 Title: After update&upgrade packages Ubuntu 13.10 Status in “xorg” package in Ubuntu: Invalid Bug description: After installing python 3.3 and python libraries and update+upgrade of the system it booted into the splash screen. Instead of displaying the desktop after the splash screen (atomatic login) the OS displayed a problem report dialog and the splash screen just stayed frozen. Everything else (webserver, minecraft server, etc. etc.) just works fine when I connect to the machine on which the OS is installed. Only the desktop of the OS will not appear.
