Hi! I have a toshiba c660-2ml laptop with nvidia 315m.

This pc hasn't a intel graphic card and for this i am supposed to use the nVidia. I have installed the natit.kext and put the fakeID 0x0a7a in clover, and during boot the natit recognize the card but when load it the monitor turn off. I think that now is the dsdt but i can't patch it. The PC work with other monitor with hdmi

Now i post the ioreg and the EFI clover with original ACPI files. I haven't installed other kext as audio or wireless because i want resolve first this issue.

Thanks in advance for the help, and sorry for my bad english.

nVidia GeForce 315M should be detected and work OOB. It's based on the GT2xxx architecture and that's fully supported.

Try the attached DSDT, it injects FeForce 315M characteristics as reported in IOReg.

Any reason why you use an iMac12,2 SMBIOS as opposed to say MacBookPro8,x? It also seems you reused a Clover config file from another system and tried to adjust it to your Toshiba. Try the attached instead, I've cleaned it up a bit. For instance, no reason to drop all those SSDT tables that were listed, to fake the real id of the GPU, to apply the Kernel Lapic patch or the KernelPm patch.

What's your exact CPU model in your Toshiba? You need to generate your CPU-specific SSDT for power management, then get rid of NullCPUPowerManagement so that you can enjoy proper CPU SpeedStep and Turbo boost.

Thanks for the reply! I have an i3-2350m but it haven't the integrated card

Not working... The PC start only with cpus=1 and when it should load the login the pc restart 

This is the PC loaded with debug, it show this kernel panic

The graphic card is correcly loaded, but the internal monitor isn't recognized. When should appear the login, the internal is black and turn off, but with external monitor or with a screen sharing the graphic works. I don't know how i can turn on the iternal monitor

Black screen will be most likely an EDID issue though, sometimes, it can also be linked to the SMBIOS.

 

Try the attached revised Clover config.

Try the attached revised Clover config.

attachicon.gifconfig.plist.zip

Not work... Black screen at the end of the boot

For EDID, i have copy the EDID of this screen by xubuntu live edition and is this:

	        00ffffffffffff0030e48e0300000000
		00160103802213780a01a59c595a9b26
		18505400000001010101010101010101
		010101010101581b567e50000e302430
		350058c2100000190000000000000000
		00000000000000000000000000fe004c

		004c503135365748342d544c4e3200c6

but it result corruptet, without Vendor ID and Product ID. The screen is changed by me two years ago because i've broken the original

The screen with nv_disable=1 work
