I have El Capitan Running, but there are GPU / LVDS problems as you can probably imagine.

If I InjectAti and set FBConfig to any of the below, I get low resolution and no acceleration.
* Galago
* Eulemur
*Bulrushes
*Hoolock

However, if I repeat the above and enable VBIOS at the same time, I get artifacts an lines on the screen before it eventually fades to black.. accept for Bulrushes. When I pair up Bulrushes with an enabled VBIOS, after the loading screen my internal display shuts off completely. I'm then able to attach a monitor externally via HDMI with full acceleration and proper resolution. The VGA or internal display does not work in this state. I've been troubleshooting for three days and I'm still where I was three days ago. Can anyone generously offer some help? Thanks!

CPU: i3 330m
