NVIDIA(0): Unable to get display device for DPI computation.

So I'm running arch on my Lenovo Y700 laptop with an nvidia GeForce GTX 960M graphics card and intel integrated graphics. The integrated graphics works fine. I've tried bumblebee and that worked, but I'd like to have to option to use the nvidia card exclusively. But when I do, it doesn't seem to recognize the monitor.

Heres my xorg.conf:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
EndSection

Section "Files"
    ModulePath "/usr/lib/nvidia/xorg/modules"
    ModulePath "/usr/lib/xorg/modules"
EndSection

Section "Device"
    Identifier     "nvidia"
    Driver         "nvidia"
    BusID          "PCI:1:0:0"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "LGD"
    ModelName      "Unknown"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "nvidia"
    Monitor        "Monitor0"
EndSection

Section "Screen"
    Identifier     "Empty"
    Device         "nvidia"
    Option         "UseDisplayDevice" "none"
EndSection

I try running 'startx /usr/bin/glxinfo' and that seems to says direct rendering is working.
Heres some output from that:

name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
...

However when I try running something like xclock or glxgears the screen freezes and I need to kill xorg in another tty. When I switch back to the original tty I ran it from it shows a bunch of output about the frames that were rendered.

heres the log from running 'startx /usr/bin/glxgears' ( /var/log/Xorg.0.log ):
