<pre>On an Nvidia optimus notebook with Intel SandyBridge GPU as primary, Weston can
only be launched when nouveau kernel module is unloaded and only one card is
present at dev/dri/
If two cards are present I have an error message:

So weston chooese the wrong card to use.
Is there a way to specify the card to use ?
If nouveau is unloaded everything works fine.
Thank you,
