@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? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
