Error is with dbus -- Skip down to **update**
I just installed F16 off of a Live CD and I've tried following some guides for installing the Nvidia proprietary drivers. I know the Nvidia driver is being used and is working, but when I logout after telling Gnome 3 to try non fall back mode all I get is a black screen and nothing happens, causing me to have to restart every time.
Like in the title, I'm using a Nvidia 560Ti. To install the Nvidia driver, I used yum to install kmod-nvidia and the x-11-nvidia-... packages from rpmfusion. Then I updated the initrd to use the Nvidia drivers. I also put nouveau as a blacklist in the kernel line in grub and put selinux into permissive. When I do lsmod I see nvidia and not nouveau. Direct acceleration by glxinfo is also at 'yes'.
There is a Nvidia X-server config program in my applications menu and when I change things like digital vibrance the display does change accordingly. And it seems to be monitoring the temp and etc correctly of the GPU.
So why is it giving me a black screen upon attempting to use Gnome 3 functionality?
Also as a side note, it appeared that the original F16 live cd couldn't run in its normal mode when I originally tried to run it. I had to run it under simple graphics mode to get it to work. And then I noticed that after I installed F16 to my hd, lsmod had vesa instead of nouveau (which only changed to nouveau after installing the kmod-nvidia stuff I think)
**update**
I think my issue is that dbus is broken. I've seen in /etc/log/messages there are dbus errors. Also upon trying to run gnome tweak it says the dbus daemon isn't running.
**update again**
It is most likely dbus, as I can't start the dbus daemon with
dbus-daemon --system as it says
Failed to start message bus: Element <fork> is not allowed in this context
Here is my /etc/dbus-1/session.conf:
