Sorry, I’m confused maybe for my bad English.
Did I should have found something related to “headless output”? I do not find anything. The only thing mentioned about intel seems to be “Chapter 33. Offloading Graphics Display with RandR 1.4”
I have XRandR 1.4. Kernel 3.11.0-031100rc5-generic. Monitor only connected to intel GPU.
My nvidia card is a GT 430. I know, not very good. But I’m interested in doing a tutorial “easy” for the novice user about how to do this that I suggest in this thread.
I have configured multimonitor (multi gpu) from the BIOS, iGPU as the primary display.
I configured the xorg.conf as shown in that link, with the corresponding BusID to nVidia, and I left uncommented ‘Option “UseDisplayDevice” “none”’.
It does not work. Plymouth appears but then it goes to the terminal.
If you tell me that this I have done is right, I could give more logs information.
When I login to the system with intel connected to the monitor and with a blank xorg.conf, “lspci | grep-i vga” shows both (intel and nvidia).
$ lspci | grep -i vga
