I woke my rig up from hibernation and got on YouTube to watch some videos, but nothing would load. Everything else was fine afaik. I rebooted since it'd been a couple days since I had last done that, but when I rebooted I got a very generic error, saying, "Oops, something happened. Log out to try again" or something whit a button that said "log out". This happens after I decrypt the drive, and before GDM shows up (In fact, I think it might be GDM displaying the message). I shut down, tried the fallback kernel (I don't remember the version #'s off the top of my head, sorry) and that didn't work, I tried Windows just in case, and then I tried the Rescue option and was able to boot into that. What could I have done to fuck up, and why did the Rescue option work? I don't see anything changed here.
Nvidia card?
...yeah. 750 Ti. Do you think it's the drivers? I installed the Nvidia drivers a while ago but haven't really had a problem with them
EDIT: I checked, and the Rescue mode, which I'm still booted in, is using the Nvida drivers, so I'm not sure its an issue with that.
are you in X?
Yeah, Wayland never worked for me on this system. Or are you asking if the rescue mode booted up a graphical environment? If that's what you're asking, yes, Gnome is up and running fine.
are you using open source drivers or the nvidia ones?
Nvidia. The Noveau drivers were installed stock but I had to switch to the Nvidia drivers to play Metro: 2033. I've been running on them for the past week or so I'd say without any problems.
ok try running "sudo dnf update"

Dependencies resolved.
Nothing to do.
Complete!
I ran a DNF update last night, maybe something went wrong during that update? I'm going to try to boot back into the regular kernel version just for shits and gigs. Maybe the rescue option did something to fix whatever I broke. Be back in a few.
No luck. The kernel I was running on was 4.4.6 and the old kernel was 4.3.4, which is also what the rescue more runs, according to "uname -r"
try adding "single" to the kernel boot parameter for kernel 4.4.6.
How would I do that and what exactly would that do?
when grub come up. select kernel 4.4.6 and press e. then find something called initramfs and add single to the end of it.
This will disable the x server at the bootup.
The only line that menitoned initramfs was "initrd16 /initramfs-4.4.6-300.fc23.x86_64.img" and when I added "single" to the end of that line, I got a kernel panic. I tried just adding a line that said "initramfs single" and it complained that intiramfs wasn't a command and then booted to the "Oops" screen again.
whoops. not initramfs i meant linux.
No worries, I'll try it again and see what happens.
Okay so that worked, and I checked the system logs. It looks like it has something to do with the Nvidia driver, I found this chunk of text that was complaining about Nvidia messing up the kernel
looks like the open source driver is loading at boot with the nvidia driver.
You mean they're trying to load at the same time?
conflicting drivers. they are loaded at the same time and cant share resources
try entering "sudo echo blacklist nouveau >> /etc/modprobe.d/blacklist"
