Doc Text:	Synaptics dependency removes _xorg-x11-drivers_ Later releases of Red Hat Enterprise Linux 7 contain the `xorg-x11-drv-libinput` driver for X, which can potentially provide a superior experience for some input devices. Users attempting to switch to `xorg-x11-drv-libinput` can try removing the `xorg-x11-drv-synaptics` driver, which is required by the _xorg-x11-drivers_ package. However, removing synaptics requires removing _xorg-x11-drivers_. To work around this issue, remove _xorg-x11-drivers_. This package exists only to install a reasonable collection of drivers at system setup time, and removing it has no runtime impact. Any X driver already installed will be updated as expected.

Description Oliver Ilian 2017-11-23 17:23:50 UTC

Description of problem:
When switching from synaptics to libinput the removal from xorg-x11-drv-synaptics removes xorg-x11-drivers, leaving all the installed xorg-x11-drv rpms without a dependency.

Please allow xorg-x11-drivers to also consider the installed xorg-x11-libinput rpm.

Version-Release number of selected component (if applicable):
RHEL 7.4

How reproducible:
always

Steps to Reproduce:
1. perform a standard RHEL 7.4 install 
3. yum install xorg-x11-drv-libinput
4. yum remove xorg-x11-drv-synaptics

Actual results:
xorg-x11-drivers is removed, leaving all installed xorg-x11-drv* rpms without dependency 

Expected results:
xorg-x11-drivers also accepts the installed xorg-x11-drv-libinput

That shouldn't be true. evdev is still installed by default and knows what touchpads are. Granted it's not as _good_ at driving touchpads as synaptics is, so this probably should be reverted.

I think we can just drop this build from the errata; I'll update the spec in git to revert the change as well.
