Hi,
As a consequence of rolling out CR updates on Latitude E7470 (Skylake chipset), X would no longer start until I rolled back all of the xorg-* packages. And to be more precise, looks like the culprit is xorg-x11-drv-intel:
https://bugzilla.redhat.com/show_bug.cgi?id=1445583
as the CR package release version matches the one mentioned in Comment #2, in the regression context.
I've already submitted a bug report: https://bugs.centos.org/view.php?id=13717
so I just wanted to bring this issue to attention of anyone who's running this chipset/VGA.
Thanks, Milos.
