Hello!
No updates for days until 2015-04-01. Then presented with huge steaming pile of updates all at once, apparently related to Centos 7.1 release.
Not thinking about it being April Fools Day, I immediately did:
yum -v check-update, then
yum -v update
then rebooted.
After reboot, there is a problem with the video. It seems to flicker when the mouse pointer touches the screen edges. Also, sometimes when viewing pages in Firefox, the window becomes partially covered with horizontal black lines.
During reboots, before the login screen appears, there are quickly disappearing messages seeming to include references to "drm:9" and some sort of "underrun".
In the terminal window, I get a message:
ABRT has detected 3 problem(s). For more info run: abrt-cli list --since 1428078184
When I do that, I get:

The Autoreporting feature is disabled. Please consider enabling it by issuing 'abrt-auto-reporting enabled' as a user with root privileges.
So is this line where the problem may be?:
drivers/gpu/drm/i915/intel_display.c:869 intel_wait_for_vblank+0x211/0x220 [i915]()
Started to search online for information, but quickly decided:
1) available info is over my head
2) when in a hole, stop digging
So, any obvious answers, other than a complete reinstall?
Note: I really thought Centos is about reinstalling after years, not months. Grrr . . .

Well, it could be the same, but the bug report does seem to refer to the bug being in kernel series 3.18. I am just using whatever 3.10 series kernel comes standard with Centos 7.x.
I don't know anything about bug reports, and I an not familiar with swapping out kernels in Centos.
BTW, is El Repo another name for the EPEL repository?

Well, the CentOS kernel is a 3.10 kernel in name (or number) only. Red Hat backport much stuff from later kernels, and in this case that includes much broken code for the Intel i915 driver. The code is broken from around 3.15 and still not completely fixed in the current 4.0-rc6 code base. Updating to a newer kernel, and hence a newer i915 driver, may or may not help, but it doesn't hurt to try.

Is there a way in Centos 7 to boot into an alternate video setup?
Some distributions have an option to boot into something called VESA (or something similar). Something that might not have the fanciest features, but more likely to at least just work.

I can confirm the problem on Nvidia GTX 750/760 with kmod-nvidia 346.47 proprietary driver from elrepo. As a workaround you could try to set PowerMizer mode to maximum performance using nvidia-settings utility.
I am not sure if that related to OP, or if that relates to elrepo release, but it looks like the bug was introduced in update to 7.1.

issue.
Does this look like your bug:
Yes, that is very much like the problem I encountered, but in my case it did not need multiple monitors to happen, just one. The config file suggested did seem to fix the problem, at least serving as a (hopefully) temporary workaround.
Johnny, thanks for the pointer. And thanks to all who replied.
P.S. - the workaround seems to work with both the latest "standard" Centos 7 kernel and the ML kernel from the El Repo repository. But today's X11 updates (done before the config file was done) made no difference.

Does this look like your bug:

I spoke too soon. Although the screen flicker has been worked around, I still intermittently get lots of horizontal black lines when going to gmail. No other distribution shows this problem, only Centos 7, and only after the 1503 updates.

Yes, that is very much like the problem I encountered, but in my case it did not need multiple monitors to happen, just one. The config file suggested did seem to fix the problem, at least serving as a (hopefully) temporary workaround.
Johnny, thanks for the pointer. And thanks to all who replied.
P.S. - the workaround seems to work with both the latest "standard" Centos 7 kernel and the ML kernel from the El Repo repository. But today's X11 updates (done before the config file was done) made no difference.

Is there a way in Centos 7 to boot into an alternate video setup?
Some distributions have an option to boot into something called VESA (or something similar). Something that might not have the fanciest
features,
but more likely to at least just work.

Updated the kernel as suggested to 3.19, did not solve problem. Unbelievable! Oh, well . . .

What a shame; I hadn't planned on spending Easter weekend learning to
do
kernel upgrades, but . . . here it goes.

Well, the CentOS kernel is a 3.10 kernel in name (or number) only.
Red
Hat backport much stuff from later kernels, and in this case that includes much broken code for the Intel i915 driver. The code is
broken
from around 3.15 and still not completely fixed in the current
4.0-rc6
code base. Updating to a newer kernel, and hence a newer i915 driver, may or may not help, but it doesn't hurt to try.

No, they are two completely separate repositories:
