Which Video card do you have in the t420s ? my t430s has an Intel one
(00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core
processor Graphics Controller (rev 09) ) and it works fine, but I had
the same issue on my kid's workstation, using onboard Nvidia chipset.
The issue appeared only after the 7.0.1406 -> 7.1.1503 update. What I
did was just install cinnamon and now my kid uses it when logging
through gdm.
I've never had time to investigate the gnome3/gnome-shell issue, but
wondering if there was a mismatch between hardware and software rendering.
Can you try to just install CentOS 7.0.1406 (LiveCD would be enough to
test) and see if that works ? That will not fix the issue for a yum
update though, but at least that would give directions.
