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. - -- Fabian Arrotin The CentOS Project | http://www.centos.org gpg key: 56BEC54E | twitter: @arrfab -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iEYEARECAAYFAlXmkR0ACgkQnVkHo1a+xU6ibgCghtwPTPPYxu1jmMjciXisteZk +S8AnA2CkHtCniLjYlAEvqFkizYZrfh0 =IMfj -----END PGP SIGNATURE-----
