Comment 2 for bug 187444

Sorry about the waffle earlier.

I have included the xorg.conf I crafted "xorg.conf.orig"

And one the restricted driver manager generates after doing either:

a) enabling nvidia restricted driver
b) via "preferences -> appearance -> visual effects" which then launches the restricted driver manager because it thinks, wrongly, that the "nvidia" driver is not set.

This generates and xorg.conf as seen in:- "xorg.conf.after_enabling_though_restricted_manager"

I have included TWO lspci outputs. One with the nvidia card enabled, the other with the intel card enabled. Only one can be active at once and changing over requires using the front switch, and rebooting. In other words only one card can be mapped in at any one time at power on.

WORKAROUND: I've found a workaround, which is to move the nvidia driver section to be the first in xorg.conf. The restricted driver manager / visual effects then works as expected and does not make any changes to xorg.conf

It appears therefore that only the first "Device" section is examined / modified. Which if I put "Intel" first, is the wrong one.
With the workaround Xorg works. (Except I think the wrong libGL is loaded, but that is something else not directly related to this bug report I guess)

My setup is a bit unusual, but on the other hand it's probably not that outlandish.
