Catalyst 12-8 does not support Xserver 1.13 and is not going to work on Ubuntu Quantal/12.10. You should remove 12-8 and just use the version found in Ubuntu repo (or manually install Catalyst 12-11 beta).
This is not a bug with Ubuntu's fglrx package, so marking Invalid. ** Changed in: fglrx-installer (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/1070305 Title: amd catalyst driver installation fails Status in “fglrx-installer” package in Ubuntu: Invalid Bug description: after installing catalyst 12.8 on ubuntu 12.10 unity cant start anymore ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: xorg 1:7.7+1ubuntu4 ProcVersionSignature: Ubuntu 3.5.0-17.28-generic 3.5.5 Uname: Linux 3.5.0-17-generic x86_64 ApportVersion: 2.6.1-0ubuntu3 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: None Date: Tue Oct 23 13:27:32 2012 DistUpgraded: Fresh install DistroCodename: quantal DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Advanced Micro Devices [AMD] nee ATI Cypress XT [Radeon HD 5870] [1002:6898] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited Device [174b:e177] InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MachineType: Gigabyte Technology Co., Ltd.
