Doc Type: Enhancement
Doc Text:
.*Mutter* now allows for mass-deployable homogenized display configuration The *Mutter* window manager now makes it possible to deploy pre-set display configurations for all users on a system. As a result, *Mutter* no longer requires that the configuration for each user is copied to its own configuration directory, but it can use a system wide configuration file instead. This feature makes *Mutter* suitable for mass deployment of homogenized display configuration. To set the configuration for a single user, create and populate the `~/.config/monitors.xml` file. For the login screen in particular, use the `~/gdm/.config/monitors.xml` file. For system-wide configurations, use the `/etc/xdg/monitors.xml` file.

Description Joe Wright 2018-05-29 19:21:42 UTC
Description of problem:
- As things currently stand, mutter and/or ~/.config/monitors.xml overrides xorg/xorg.conf, and cannot use a generic configuration. It flatly requires that the configuration be defined using display serial numbers (in current versions, including in Fedora 28). This creates a major problem for mass deployment where it is not feasible to know display serial numbers. Additionally, the configuration used to be read from /etc/gnome-settings-daemon/monitors.xml but that seems to have been dropped. This change would need to be reverted in addition to a method to allow "generic" non-serialized display configurations for the purpose of mass-deployment/automation/homogenization

How would the customer like to achieve this? (List the functional requirements here)  
- A generic display configuration can be passed via kickstart post-install script/ansible/some other deployment automation solution that sets the default display configuration

Is there already an existing RFE upstream or in Red Hat Bugzilla?  
- No
Does the customer have any specific timeline dependencies and which release would they like to target (i.e. RHEL5, RHEL6)?  
- As soon as possible
Is the sales team involved in this request and do they have any additional input?  
- No

List any affected packages or components.  
- mutter
- gnome-settings-daemon
- control-center

Would the customer be able to assist in testing this functionality if implemented?
- Yes
