Just had this problem. In my case looks like some other program (was trying to install openbox) RENAMED amdpcsdb.default to amdpcsdb. , causing this file missing error.
Renaming amdpcsdb. to amdpcsdb.default (just added .default file type) fixed perfectly the problem, in my case. I'm at Debian Wheezy, ATI Radeon 7520, Toshiba Satellite Notebook C855D. That's all folks, Bruno -- 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/440233 Title: fglrx fails at startup because of missing amdpcsdb.default + removal leaves bad settings in Xorg.conf Status in fglrx-installer package in Ubuntu: Fix Released Status in fglrx-installer source package in Karmic: Won't Fix Bug description: Binary package hint: xorg-driver-fglrx OS: Ubuntu 9.10 (Karmic) ~ Beta 1 (64-bit) After messing around with ATI graphics drivers all day, I'm now stuck in this situation: Installing fglrx via the restricted hardware manager leaves my system unbootable. The Xorg.0.log reveals the following: (II) ATI Proprietary Linux Driver Version Identifier:8.66.10 (II) ATI Proprietary Linux Driver Release Identifier: 8.66.1 (II) ATI Proprietary Linux Driver Build Date: Sep 3 2009 21:35:39 (EE) Unable to initialize PCS database (EE) Missing PCS defaults file /etc/ati/amdpcsdb.default (EE) No devices detected. Manually removing fglrx packages via the recovery console leaves the system even more unbootable: (II) LoadModule: "fglrx" (WW) Warning, couldn't open module fglrx (II) UnloadModule: "fglrx" (EE) Failed to load module "fglrx" (module does not exist, 0) (EE) No drivers available. Manually removing xorg.conf makes the system bootable again (probably using the ati driver). I have the following files on my system that might be relevant: /etc/ati/amdpcsdb /etc/ati/amdpcsdb.default.dpkg-bak ubuntu-bug has attached all kinds of stuff for me.
