nvidia-prime with kernel 3.12 in Ubuntu 13.10 does not load gnome-settings-daemon

[Sayantan Das]

To get the true powersavings mode and GPU switching abilities, I installed kernel 3.12.5, nvidia-331, nvidia-prime on my Ubuntu 13.10 x64bit. I have Nvidia GeForce 310M optimus card. This combination is causing the ambiance to function improperly. If I run gnome-settings-deamon, it gives me the error

    (gnome-settings-daemon:5089): Gdk-ERROR **: The program 'gnome-settings-daemon' received an X Window System error.
    This probably reflects a bug in the program.
    The error was 'BadMatch (invalid parameter attributes)'.
      (Details: serial 173 error_code 8 request_code 140 minor_code 30)
      (Note to programmers: normally, X errors are reported asynchronously;
       that is, you will receive the error a while after causing it.
       To debug your program, run it with the GDK_SYNCHRONIZE environment
       variable to change this behavior. You can then get a meaningful
       backtrace from your debugger if you break on the gdk_x_error() function.)
    Trace/breakpoint trap (core dumped)

The xorg.conf is

You won't get the power savings in 13.10, not even installing the packages that you mentioned.

As for the error in the gnome-settings-daemon, it's really LP: #1224254 (make sure to get libgnome-desktop 3.8.4-0ubuntu1.1)
