[Bug 312756] Re: support graphics card hot switch

 

Yes an ideal world ,sounds like windoze  ?.nvidia's binary wont support it ?,if they back ported ( cough) or allowed the windows port ( developed on nux -with emacs & closed source) for use in linux it all would make sense and the X server
would need an update to support more than the current multi-seat capabilities that it currently supports ,which can pull
two screens together which is somewhat occurs in windoze.

This says it all ,so until this changes multiple hacks of dsdt's ,wmi drivers ,and hacked concurrently will be required to get 
things to work ,and /or Nouveau has reached further dev.
