We already have a redesigned Settings panel for external displays in F20. We'd
need to get more into specifics here (how many monitors, whether they're completely
static, where the main monitor is, and whether the problem is usage after the desktop
is setup, or really problems in setting up a specific layout).
The problem I have been having is that I have configured Xorg to
rotate my four montiors, but that configuration is ignored and/or
overridden by GNOME with GDM starts.
I finally figured out the fix:
1. Make sure the Xrandr plugin is enabled:
gsettings set org.gnome.settings-daemon.plugins.xrandr active true
2. Use the Display Settings control panel to set things up the way I want.
3. Manually copy the file ~/.config/monitors.xml to
Step #3 was the unexpected and un-user-friendly step. None of this
was documented that I could find.
I think I had originally disabled the xrandr plugin in older Fedoras
because turning off a monitor caused all hell to break loose--the
monitor positioning/rotation was scrambled and in some cases it
wouldn't come back correctly at all without restarting the X server
(maybe driver bugs here).
So, there are several problems here. First, all the documentation out
there that says to use /etc/X11/xorg.conf to configure your
multi-monitor setup system-wide doesn't work with Gnome 3 on Fedora 19
in my experience.
Second, there is no discoverable/documented user-friendly
way to set the system-wide/GDM monitor configuration.
Third, there may be some bad interactions with the Xrandr plugin in
the face of hardware configuration changes or simply powering off/on
