A user running gnome came in this morning, clicked on the application menu... and it was much shorter than he expected. He could get to firefox, and googled about refreshing that... and found something that told him to reboot.
And that's it: I cannot get X up, at all. I just get the "oh, no, something failed, please log out and try again".
Fully updated CentOS 7, [AMD/ATI] Oland [Radeon HD 8570 / R7 240/340 OEM], and, like most of us, he uses two monitors. . I've tried removing the xorg.conf, and renaming /etc/X11/xorg.conf.d/20-fglrx.conf, which was there (I didn't put it there when I built the box a few months ago.)
What if you boot into runlevel 3 (that is no gdm or kdm...), log in into virtual console, rename all X related stuff in /etc, and from command line execute
startx
? What do you get spit on console, and what do you get in xorg log?
Incidentally, do you have security system that watches file changes? That may tell you a lot. As an alternative, you may take a look at differential backup - whatever was newly backed up may tell you a story. Unless backup uses timestamps, and timestamps were fiddled with when change happened.

I don't see anything even vaguely useful in the Xorg logs... and, for that reason, not sure why I'm on Xorg.3.log, other than it may have been created by startx. I've tried that, both as root, and as myself, get that "oh, no" screen, and when I hit enter to log out, I get a live but black screen, completely unresponsive.
I don't see any errors in dmesg or messages, and I've tried reinstalling xorg-x11-drv-ati, which gives me xorg-x11-drv-ati-7.6.1-3.20160215gitd41fccc.el7.x86_64.
Does anyone have any ideas on this? I can't even get a single screen working, though it's mirrored, of course, in text mode.
