How should I configure Xorg for an intel integrated graphics card under Fedora 25?
My motherboard and i7-6700K are supposed to support a dual monitor setup, but Xorg (or is it Wayland?) fails to detect the hardware on a level where this is possible. It seems to be using a VESA driver.
There are some smaller issues such as the system locking up when I change video modes (Xorg -> terminal). I assume these will be corrected by fixing the driver problem(s). There are some forum posts about adjusting BIOS settings or setting
i915.enable_rc6=0 - I will worry about this later.

I did have a GeForce card and the NVidia drivers were installed. It has been removed and the drivers uninstalled. The "nouveau" driver is still blacklisted for modprobe.
The kernel version is new enough that
i915.preliminary_hw_support=1 boot flag should not be necessary. The i915 driver is loaded during the initial boot.
Someone said that I should not even use the Xorg
intel driver. I have created Xorg configurations to force the usage of the
modesetting drivers. Neither allows Xorg to start. Apart from this configuration file, the only autoloaded configuration files I can find are for input devices like keyboards and mice.
As you can see from the Xorg log, I do not have these device files:
What drivers am I supposed to use, and what is the recommended configuration?
