So last night I resolved an issue with my updates not actually installing. So honestly IDK what all was in there.. I know there was some nVidia drivers from RPMFusion in teh mix (due to a new 1070Ti being installed), I recall some KDE bits, and likely a new kernel. So anyway 1200-ish updated packages installed and after a reboot I get a black screen.

So more accurately, I get the normal bios splash, the generic Fedora boot screen with the 3 white rectangles then black. Keyboard unresponsive, mouse unreponsive.. nothing works. So I rebooted, hit E to edit my grub line and added '3' to the end of the appropriate line.. and gained a text login. So right now I'm at an impasse. I know this issue has been encountered by so many people over the years, but never by me. The game plan is to look through the dnf update history and remove any nvidia packages if they were installed, and give a reboot a whirl. Maybe even unblacklist nouveau.

Any advice on a better way to tackle this? Thanks

So turns out that in order to fix this I had to reinstall F28. I kept my /home and /etc volumes but all the rest was wiped. Was able to install the RPMFusion drivers and things just worked.

I had a similar issue. Had a look at journalctl and found these:

Aug 26 15:38:36 localhost.localdomain systemd[14950]: selinux: avc:  denied  { reload } for auid=n/a uid=42 gid=42 cmdline="/usr/libexec/gnome-session-binary --autostart /usr/share/gdm/greeter/autostart" scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=system permissive=0

Aug 26 15:37:02 localhost.localdomain setroubleshoot[1873]: SELinux is preventing gnome-session-c from map access on the chr_file /dev/nvidiactl. For complete SELinux messages run: sealert -l fe42c09d-f6fa-4129-9237-af3b65ed300e

Decided to try and disable SELinux (set SELINUX=disabled in /etc/selinux/config) and the problem went away.

Will wait a bit and see if it's fixed before I enable SELinux again.

If that doesn't work, you may need to undo that update. I'm not sure, as I've never needed to do it, but i think that the right command is:

sudo dnf history last undo

although I may have the order wrong. Once you've done that, reboot and see what happens. If it works, you can get a list of needed updates and apply them a few at a time followed by a reboot, and see where it fails. If not, you're probably no worse off than you were before.

Good idea. I hate rolling back but sometimes you gotta.

Tried this.. sudo dnf history | head showed me the transaction that installed nvidia, except an unknown error keeps me from undoing that transaction. In addition, I'm unable to just remove nvidia because there are so many dependencies now. Chrome, plasma, lots of things. So now Im screwed.

I had this happen too. For me, the problem was that the configuration somehow was changed to not target a multi-user GUI boot anymore. See this.

No dice. Tried last night and still booted to black screen.

Does systemctl start gdm work for you?
