Description of problem:

After upgrading from Fedora 22 to 23 using fedup.

gdm would flicker rapidly between text Linux console and X for about 5 minutes.  After that had stopped, attempting "startx" showed an error in the Nvidia driver regarding the ABI version of the xorg-server in Fedora 23.  Updating the nvidia driver to the latest version (358.09 at this time) did not help.  Copying /usr/bin/startx to /root/ then editing it to add the "-ignoreABI" parameter allowed the server to start but it quickly crashed back to the console.


Version-Release number of selected component (if applicable):

Fedora 22 with manually installed NVIDIA-Linux-x86_64-358.09.run package downloaded from nvidia site.


How reproducible:

With the nvidia drivers from the nvidia website manually installed on Fedora 22, upgrade to Fedora 23.


Actual results:

Xorg cannot start.


Expected results:

Xorg should start.


Additional info:

Using the negativo 17 provided yum repository to install the custom compiled version of the nvidia drivers does work as expected.
