F21: Gnome doesn't work on i686 Dell Laptop

[Max Pyziur]

Greetings,

Recently, I "fresh installed" F21 on a Dell i686 Inspiron Laptop.

I had been running F18 on it, and just wanted to jump to the newest 
release w/o stepping through F19 and F20. I kept the /home partition, and 
wiped everything else out.

Xfce and Mate Desktops start and are very functional.

Any variant of Gnome (new version and Classic) reports an equivalent 
screen-of-death with the message reading "A problem has occurred, and the 
system can't recover."

The /var/log/messages file is very extensive; it begins with:
Mar 18 19:06:49 MercToo systemd-logind: New session 14 of user pyz.
Mar 18 19:06:50 MercToo org.a11y.Bus: g_dbus_connection_real_closed: 
Remote peer vanished with error: Underlying GIOStream returned 0 bytes on 
an async read (g-io-error-quark, 0). Exiting.
Mar 18 19:06:50 MercToo org.a11y.atspi.Registry:

Exiting.

Mar 18 19:06:50 MercToo gnome-session: ** (gnome-settings-daemon:1136): 
WARNING **: Name taken or bus went away - shutting down

...


and goes on like that.

I've done various "yum groupinstalls" hoping to get all of the various 
missing dependencies and missing libraries. Obviously, I'm missing 
something.

I noticed that someone (on a similar Gnome problem) said to check for a 
list of services using systemctl to see if they are enabled; I did that, 
and everything seems to be correctly enabled.

Is this problem resolvable on an i686 system? I'd like to resolve this 
first, before upgrading my x86_64-based machines.

I have no loyalties to Gnome; I'd just like to function close to their 
intended design. And take it as a sign of possible other problems in the 
even that they don't.
