^ and ^^ and ^^^
this information was precisely what i was searching for.
to add I found some issues with the exclusion and i always prefer the cli updates.
so, i did this.
yum --exclude=xorg* --skip-broken update
and that allowed me to update (about) 900 packages after a new install and prevent a brand new video card from getting a driver that was crashing X.
yum update was planning on 10+ xorg-X11 updates when the default one is working perfectly.
this is a time proven thread.
ASUS geforce GT 630(silent) 0dB, 2GB DDR3,
is actually an NVIDIA corp GK208 Board - 21320
and yums update was pushing unstable updates...
the above command allows all updates, while suppressing anything begining with xorg (in my case about 10 small files, the * is a wildcard ) and ignored all the dependencies associated with them.
thank you itsme_sujith, for taking the time to extend the (valuable) details, and the OP too.
