Screen resolution supported on Windows but Fedora says it isn't

I have a dual-boot of Fedora 18 and Windows 7. The result of

Code:
lspci | grep VGA
is

Code:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF106 [GeForce GT 555M] (rev a1)
After I followed this tutorial, I got optirun working, and on glxspheres I had a 11x speed increase versus without and on glxgears 2x speed increase. However, my screen resolution is capped at 1024x768 on Fedora, and on Windows 7 it's capped at 1366x768. I want the 1366x768 resolution. How can I configure it to use this resolution? The result of

Code:
xrandr
is

Code:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected primary 1024x768+0+0 0mm x 0mm
   1024x768        0.0* 
   800x600        61.0
So I cannot create new resolutions from there. Possibly I need to run with the nvidia driver, but when I run

Code:
nvidia-xconfig
and reboot GNOME Shell cannot start because it cannot load the module "nvidia". I really want a 1366x768 resolution; please help!

I found another error; when my computer hibernates and I wake it up a black screen is presented to me, and nothing I do will make the screen display anything.

Re: Screen resolution supported but Fedora says it isn't

This is likely a video driver issue, but I have no idea what I need to do to fix it. Is there any more information anyone needs to provide help?
