Bug#731265: Optimus from Nvidia does not works

[LOMBARD Maxime]

Package: nvidia-glx
Version: 319.76

Dear Mainteners,

Since nvidia driver 320.x, Nvidia has implemented partially Optimus in
their driver. Earch users which  have a laptop with Optimus technology can
enabled the Nvidia card to display the desktop rendered instead of the
Intel card.

For more explainations, you can read the readme here :
http://us.download.nvidia.com/XFree86/Linux-x86/319.76/README/randr14.html

So, i tried this solution in Debian Sid because there are the minimal
requirements :
- Kernel 3.11 (> 3.9)
- Xrandr 1.4.1
- Xorg 1.14.3
- Nvidia drivers 319.76

I follow the explainations in the readme after to install a fresh Debian
Sid :
1- Install modesetting driver (aptitude install
xserver-xorg-video-modesetting) -> Xorg and Xrandr are installed too.
2- Install Nvidia driver (aptitude install libgl1-nvidia-glx
libgl1-nvidia-glx:i386)
3- Create a "/etc/X11/xorg.conf" as explained. I replace the BUSID example
by the good ID (BUSID "PCI:1:0:0" for me) and i uncomment the
"UseDisplayDevice" line.
4- Install the rest (mate etc...)
5- Create a ~/.xinitrc with the xrandr command + exec mate-session
6- Reboot, log-in, startx and ... FAILURE !!!

The problem is after the startx. It seems to work but i have a X server
crash like this :

> X Error of failed request: BadValue (integer parameter out of range for
> operation)
> Major opcode of failed request: 140 (RANDR)
> Minor opcode of failed request: 35 ()
> Value in failed request: 0x2bf
> Serial number of failed request: 16
> Current serial number in output stream: 17
>

 To try to know if it's a problem with my laptop, i installed Archlinux and
i follow the same way like previously. Result, it works without problem.

PS : Actually i'm on Arch because it works but i love Debian so... Thanks
to help ;)
