Hi, my setup consists of nvidia pci card and onboard intel card. nvidia is the primary card as per my bios settings.I started xorg on nvidia with dual head configuration. After configuring intel as bus master I started separate instance of xorg on intel.Now on killing intel xorg i get "no signal" message on nvidia monitors. 1. xorg (nvidia) -sharevts -novtswitch -isolatedevice (nvidia) 2. xorg(intel) -novtswitch -isolatedevice (intel) i have vesafb configured with framebuffer console support. when i start nvidia xorg and kill , i am able to draw on framebuffer console when i start nvidia xorg and intel xorg , kill anyone of them i get "no signal" message on nvidia monitors and framebuffer is not available to me. please let me know if am missing anything.
