F22 Black Screen with nVidia drivers

[Christopher Ross]

Picking up the akmod failure I find this:

root at snoopy 14:11:52 ~ # akmods --force
Checking kmods exist for 4.0.6-300.fc22.x86_64             [  OK  ]
Files needed for building modules against kernel
4.0.6-300.fc22.x86_64 could not be found as the following
directories are missing:
/usr/src/kernels/4.0.6-300.fc22.x86_64/
/usr/lib/modules/4.0.6-300.fc22.x86_64/build/Is the correct[FAILED]devel 
package installed?

ls: cannot access /usr/src/kernels/4.0.6-300.fc22.x86_64/: No such file 
or directory

total 4.0K
drwxr-xr-x. 22 root root 4.0K Jul  6 14:11 4.0.6-300.fc22.x86_64+debug




So it cannot build the modules because there is no
/usr/src/kernels/4.0.6-300.fc22.x86_64/

But there is a 4.0.6-300.fc22.x86_64+debug

Does this mean I installed the wrong kernel and/or headers? If so, it 
wasn't on purpose. I've never told dnf which kernels to install, it's 
always chosen that by itself.

Thanks,
