black screen on boot with Toshiba r835 is there a dsdt fix?

Recommended Posts

I have a Toshiba R835 sandy bridge I5 with hd3000 graphics. I'm following a number of different forums and we all have the same problem. The LVDS is not recognized and the screen goes dark just after boot. I have full acceleration on my HDMI but nothing on the screen. If the frame buffer doesn't load then I get the laptop screen but no accel and 1024 x 768 resolution. I've tried a DGDT patch and the dual link patch but to no avail. Any ideas or help would be greatly appreciated by me and many others.


I'm attaching the original dsdt and the one I'm using now with the patches mentioned above plus a hpet patch that fixes my usb. Sleep, speedstep, apple hda don't work either. I'm using multishit lan kext and voodoo hda 0.2.7.3
