@Alistair: if the gpu-manager detected only one GPU, it means that the
other one was probably powered down (or it hadn't been powered on yet?).

Either way, you can work around the problem by passing the
"nogpumanager" kernel parameter on boot. This will disable the
gpu-manager. If that helps, you can make the parameter permanent in
GRUB.

Title:
  xorg.conf overwritten by booting system

Status in “ubuntu-drivers-common” package in Ubuntu:
  Fix Released
Status in “ubuntu-drivers-common” source package in Trusty:
  Fix Released

Bug description:
  Description:	Ubuntu 14.04 LTS
  Release:	14.04

  ----------------

  == SRU Request ==

  There is a regression in the gpu-manager that causes it to revert user
  changes right before the first reboot after enabling the fglrx driver
  or the nvidia driver on a system with hybrid graphics (Intel+AMD or
  Intel+NVIDIA). This causes the gpu-manager to remove the current
  xorg.conf and to switch to Mesa.

  [Impact]
   * This regression makes it almost impossible to use binary drivers on systems with hybrid graphics.

  [Test Case]
   * Make sure to be using a hybrid system with Intel+AMD or Intel+NVIDIA GPUs.

   * Make sure that the gpu-manager is not disabled (only necessary if
  you disabled it manually).

   * Remove all fglrx and nvidia drivers (keep the nvidia-common and the nvidia-prime packages):
     sudo apt-get --purge remove nvidia-331
     sudo apt-get --purge remove nvidia-331
     sudo apt-get --purge remove fglrx
     sudo apt-get --purge remove fglrx-updates

   * Install ubuntu-drivers-common from trusty-proposed.

   * Restart the system.

   * Install the binary driver (either fglrx or nvidia, according to the available discrete GPU), reboot, and check that the binary driver is enabled (attach your /var/log/gpu-manager.log)
      - Expected: the (AMD or NVIDIA) discrete GPU is enabled.
      - Bad behavior: the system switches back to the intel driver and the discrete GPU is not used, despite the fact that the system was configured properly.

  [Regression Potential]
   * Low. Systems that currently work will keep working as usual, the ones that currently fail should finally work.

  [Other Info]
   * N/A

  Hello,

  I am using a notebook with a quadcore AMD A10 and hybrid graficcard AMD/ATI Radeon HD 8650G / AMD/ATI Sun XT Radeon HD 8670A/8670M/8690M.
  After installing fglrx I generated the xorg.conf in the terminal with 'sudo aticonfig --adapter=all --initial' and it looked pretty good. Up to this point I was able to switch between the cards with the commands 'sudo aticonfig --px-dgpu' for the discrete card and 'sudo aticonfig --px-igpu' for the intigrated card to save power.
  After rebooting I realized that I was no longer able to switch between the cards and found that the xorg.conf will be overwritten whenever I modified it and reboot the system. The new (by boot) generated xorg.conf contains not the relevant information for switing between the cards.
  I attached both configuration in one file (xorg.conf.comparison). I will also provide the atisysteminfo-report.txt so far I will find the place where to attach.

  Edit: I fixed the error --> "AIGLX error: failed to open
  /usr/lib64/dri/fglrx_dri.so, error[/usr/lib64/dri/fglrx_dri.so: cannot
  open shared object file: No such file or directory]" but it changed
  not the bug of overwriting the xorg.conf.

  Regards,
  Uwe
