@Alistair: the gpu-manager detected a change in the number of the available graphics cards:
"How many cards? 1 The number of cards has changed!"
It detects the following card:
Vendor/Device Id: 10de:1004 BusID "PCI:1@0:0:0"
The gpu-manager reconfigures your xorg.conf when you physically remove, add, or disable a graphics card from the BIOS. Did you do any of this?
