Yum informed me that the driver conflicted with x11-glamor (something like that), so I removed the corresponding package.

Anyway, I rebooted, and then... nothing. System refused even to startup, and systemd suggested to me that I open journalctl (which taught me nothing). Right now I've started a Slax LiveCD to backup all my data and reinstall the whole thing from scratch. I don't have the slightest clue as to what could possibly have happened here. The only thing I wonder: could it be that installing the kmod-nvidia driver while booting to a default console (and not graphical) could lead to this weirdness? A previous installation on that machine went OK, but the difference was that the first time, I started with a full GNOME installation right away. Any suggestions? If I were to troubleshoot this I would do it the following way: 1. wipe everything and set up standard desktop set with Xwindow 2. install nvidia driver 3. remove packages you don't like and replace them with the ones you like to achieve your final configuration Why? Because all usually is tested in pretty much standard set of packages, thus if you follow the route above you will unlikely have your box bricked after installing nvidia driver. Then in step 3 you will discover doing which of your customizations breaks things. I call it for myself lazy person easy path approach ;-) Just my $0.02.

I used nvidia-detect, and installed kmod-nvidia. Even then, the previous installation ran kmod-nvidia with success on twin monitors. And even then, installing the wrong NVidia driver should only result in X failing to start... but not in a system that won't even *boot*. Startup messages stopped short immediately, I'd say right after initramfs was loaded. On a side note: before using CentOS, I ran Slackware for a few years, so I know how to configure X and video drivers manually. I've never seen this sort of weird crash.

I know that we saw the kernel panic when the nouveau driver was loaded on a el6.6 system with an NVidia K620, so perhaps when you brought in X11 you also installed the nouveau drivers? One thing I did this time was to make sure there weren't any incompatible drivers (like 'nouveau') installed *before* actually installing and configuring kmod-nvidia. Now everything works as expected. The elrepo nvidia drivers will disable the nouveau driver automatically so you don't need to worry about things like that. Don't over-think it. I would recommend you just set up your system the way you want it with at least a minimal working Xorg installation, and fully updated. Then just: yum install nvidia-detect yum install $(nvidia-detect) and reboot, and you should be good to go. I can't be sure 100 %, but I think this was the culprit.
