Fedora switched from using the synaptics touchpad driver to libinput(?)
by default. Unfortunately, the libinput driver doesn't appear to have
all the features that the synaptics driver does.
At least in Fedora 27, you can uninstall the xorg-x11-drv-libinput
package and install xorg-x11-drv-synaptics-legacy. I'm not sure how
long this will last.
I'm using libinput (/usr/lib64/xorg/modules/input/libinput_drv.so) on a
Dell Inspiron N7110 laptop running F27 and vertical scroll works just
peachy for me using two fingers on the touchpad. I see these entries in
the /var/log/Xorg.0.log file:
[ 109.192] (**) AlpsPS/2 ALPS GlidePoint: Applying InputClass
"libinput touchpad catchall"
[ 109.192] (II) Using input driver 'libinput' for 'AlpsPS/2 ALPS
GlidePoint'
YMMV (your mileage may vary)
