Hallo Alberto,

I followed your instructions, including the installation of the 
ubuntu-drivers-common from the proposed-archive.

The result was, that the xorg.conf wasn't changed anymore after reboots.

BUT the output from /var/log/gpumanager.log says: Disabled by kernel 
parameter "nogpumanager"
Before that I had the gpu-manager disabled via the grub parameter 
nogpumanger to prevent my xorg.conf from being overwritten. But 
following your instructions, I deleted this parameter and updated grub.
I doublechecked my /etc/default/grub: There's no such parameter.
Did this happen intentionally via the new ubuntu-drivers-common-package 
or did I miss something?
Is it possible that there's a lock-file somewhere not working right?

What exactly is the downside of a not-working gpu-manager when 
proprietary drivers are installed?

Thanks a lot in advance


Best regards

Philipp

>    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.
