NVIDIA Bug Report log from Fedora 23 configuration.

Description of problem:
Stereo will not activate under RHEL 7.2 or RHEL 7.1 after GNOME update.

Version-Release number of selected component (if applicable):
Issue introduced between gnome-session 3.8.4 and 3.14.0

How reproducible:
100% of the time

Steps to Reproduce:
1. Install the NVIDIA driver
2. Configure stereo mode 10 via `sudo nvidia-xconfig --stereo=10`
3. Restart gdm
4. Run `glxgears -stereo`

Actual results:
Stereo does not activate, and there is no notification that stereo is activating.

Expected results:
A notification that stereo is being enabled appears onscreen, then stereo activates.

Additional info:
Issue does not occur under other window managers, and issue does not appear to be resolved under Fedora 23 (GNOME 3.18.4). NVIDIA driver 361.28 was used in my most recent testing, but earlier driver versions also exhibit this issue. This may also occur on other stereo modes (stereo mode 4 would likely be easiest to use without a 3D Vision-capable display), but this was not tested.
