If KDE is the only or primary desktop you plan to use, sddm is preferred over
gdm as display manager. If you're a long time KDE user, I suggest you consider
kdm instead. Even though it's no longer "supported", it remains available, and
it maintains a larger feature set than sddm or lightdm, probably more than gdm
(which I never use) as well.

I booted a 64-bit F25/Plasma installation with an older Radeon gfxcard and got a
segfault that looks like yours. So I rebooted to F24/Plasma, which succeeded to
produce the attached xorg.conf. It contains mostly components that have nothing
to do with any pointing device. The following subset of the attachment should be
all you need as a starting point for pointing device customization:

Section "ServerLayout"
	Identifier     "X.org Configured"
	Screen      0  "Screen0" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
	Identifier  "Mouse0"
	Driver      "mouse"
	Option	    "Protocol" "auto"
	Option	    "Device" "/dev/input/mice"
	Option	    "ZAxisMapping" "4 5 6 7"
EndSection

I've not needed customization of any pointing device in probably at least a
decade, so am unsure that there are any specific changes to suggest. I do wonder
whether and why mouse configuration in desktop settings would not be easier than
editing config files.

I also suggest that your file be named /etc/X11/xorg.conf.d/25-mouse.conf

Finally I believe you should file a bugzilla.redhat.com bug about the segfaulting.
