Your problem has nothing to do with this bug report.

You are (or the X server is) trying to use nouveau and nvidia drivers at
the same time, which is known to cause havoc and should not be
attempted. All the fallout you described fits perfectly.

The simple fix for you is to define Driver "nvidia" in your xorg.conf.
That prevents probing of any drivers and uses only what you want.

If you feel there is bad behavior in the X server, when it probes
different drivers, you should file a bug against the X server. But
first, make sure your distribution has not patched the X server driver
probing code, e.g. by adding drivers not present in the original driver
list. If they have, you should complain to your distribution.
