sgilbert Posted December 31, 2015 Share Posted December 31, 2015 Im stuck. I followed rampage's method 3 for the 900 series Nvidia for DSDT injection. because there is no mention of the K1100M. This method has inject nvidia = false in clover config, I don't know if that is correct. I have not found out yet how to set the boot-display-port number. When I try to boot with the injected DSDT and remove the nv_disable=1, then i get BLACK screen. Ill keep looking for the boot display port option.

sgilbert Posted January 2, 2016 Share Posted January 2, 2016 So from your signature you have the 1920x1080 display on the m4800, I have the QHD+ display and I believe this is connected through eDP port only so I cannot use Intel Graphics. Am I missing something. In one of the above posts I saw someone with this laptop and the QHD+ display working on built-in. I am trying the clover injection, and I can change the boot-display, but everytime it boots to black screen. Link to comment Share on other sites More sharing options...

I don't think so. Why QHD+ system do not have intelHD (optimus enable): + intel HD 4600 can not support with QHD+ resolusion -> the main reason for Dell disable optimus. + nvidia K1100M can support with 4 display 4k i sure your system easyer more than my system because Real Mac not support with eDP ( only support with LVDS, HDMI, DP, DVI ). my connector is eDP : Link to comment Share on other sites More sharing options...
sgilbert Posted January 3, 2016 Share Posted January 3, 2016 It appears that Linux Mint provides a different output than Ubuntu Live.

Any thoughts, I don't know if there is a way for mac to use eDP port, with nvidia. If I connect to HDMI everything is working, or if I disable nvidia I can get my laptop screen to have picture, just not accelerated graphics everything is choppy and only at low resolution.

Administrators Hervé Posted January 3, 2016 Administrators Share Posted January 3, 2016 If you disable nVidia discrete GPU, I guess you fallback on the integrated Intel HD GPU. i7-4710MQ is Haswell CPU with HD4600 integrated graphics, so you will gain graphics acceleration by: forcing your HD4600 id from mobile 0416 to desktop 0412 (DSDT patch or Clover overwriting for instance) use Rehabman's Fake PCI id kexts (use FakePCIID + FakePCI_Intel_HD_Graphics + FakePCI_Intel_HDMI_audio kexts) Link to comment Share on other sites More sharing options...

Administrators Hervé Posted January 3, 2016 Administrators Share Posted January 3, 2016 My mistake I forgot to mention that you need to specify the correct Azul frame buffer too. In the case of a laptop, the correct AzulFB to use is usually 0x0a260006, i.e. #12. If you boot with Chameleon/Enoch, you may experiment with boot loader option IntelAzulFB=xx where xx is in the range 0 to 15. With Clover, you specify the FB with parameter ig-platform-id in hexadecimal string. Link to comment Share on other sites More sharing options...
