I know that the nvidia driver is proprietary software.

Neither F22 nor F23 will boot on my laptop with kernels from the last 2 week or so and the latest nvidia drivers.  When I attempt these kernel/driver combinations, it stops on the console screen which then begins flashing about once per second.  My laptop boots normally and runs fine if I use the nouveau driver.

Does anyone know the cause or a work around for this situation ?

Background Info

Laptop: Dell XPS17, i7, 16 GB, SSD
Video Card: NVIDIA GF116M [GeForce GT 555M/635M] rev a1
Linux experience: been using Fedora since RH8
OS experience: F21 and previous releases ran perfectly on this machine

Current kernel: 4.2.2-300.fc23  x86_64
Current driver: 352.41-1, built by akmod.  Log says it built and installed properly.

I first observed the issue with a couple kernels in F22.  I avoided them and ran with older kernels.  When I updated to F23, for other reasons, the kernels that ran became unavailable.  Now I have no kernels that will run with the nvidia driver.

I might be jumping the gun saying this is a video driver problem.  All I know is the console freezes during boot and the screen flashes.  I could try to get an image of the screen content with my SLR if it would help.

This is my first post to the testing list.  Be gentle !

Also: where is the correct place to get nvidia updates from ?  Right now I am using rpmfusion=rawhide.  But I've seen people stating they are using a newer nvidia driver.  Where are they getting it from ?

Thanks.
