When booting on any kernel later than 4.5.7-300.fc24.x86_64, I get a blank screen -- No source, monitor LED goes yellow. I have the following installed:


Graphics card is:

; /sbin/lspci | grep -i vga
13:01:00.0 VGA compatible controller: NVIDIA Corporation GM204 [GeForce GTX 970] (rev a1)

This bug could be it...

Any work around?

From journalctl:

Jul 20 14:06:57 localhost.localdomain kernel: nouveau 0000:01:00.0: DRM: Unknown-1 has no encoders, removing

So, what graphics adapter do you have installed?

In order to have a bootable system, make sure you remain with one of the 4.5.x kernels during the next update processes. You can also (temporarily) increase the number of kernels to keep: Set installonly_limit to maybe 5 in /etc/dnf/dnf.conf.

@RealPlayerCraft: Monitor LED.

@florian: Yes, I set installonly_limit=7 as I am paranoid. The graphics card is a GTX970. Is that what you meant by graphics adapter?

7 is a lot but OK if you /boot is large enough.

GTX970 is the problem! Google for it. There are report of a bug that doesn't let 4.6 kernels boot with this hardware. Stick to 4.5 kernels until problem is fixed - not a big deal, right?!

You can always get some extra room by removing the oldest kernel that you know doesn't work.

Apparently, this is finally fixed for 4.12.X kernels which are not yet supported by Fedora 24/25/26… Pathetic!

As you already mentioned in your question, this seems to be a bug that has been reported here:

Since this seems to be a permanent problem with no real chance of getting fixed, I have the simple question: Will I get Fedora to display something if I replace my GTX 970 with a GTX 1070 or will it be the same?

Then ask a question instead of answering one…
