Yes, by default, “startx” creates an X for the integrated Intel card only and the add-on nVidia card is not managed by X – there is only a Fedora logo (showed by framebuffer somehow) in the center of the monitor. I killed the X by “init 3” and used “Xorg –configure” to generate an xorg.conf.new and copied it to /etc/X11/xorg.conf. Later I removed other definitions of screen but kept the one for nVidia, and “startx” could create an X for the nVidia! The issue is: I can't create 1 X that can manage 2 cards at the same time(according to some info in x.org, it’s said this should work(?)), and I also can't create 2 X servers that use 1 card respectively. So, though I can't make the 2 cards work at the same time, at least I can manually switch between them by modifying xorg.conf and restart X...
