Nvidia K3100m glitches on m6800

Recommended Posts

Hi guys,

I just installed El Capitan on my Dell Precision m6800, but:

- with no args at the boot the display is black;

- with nvda_drv=1 the display is black;

- with nv_disable=1 the display works, but with strange glitches since the login screen and when I play a video file.

I think that it's a GPU issue. I have the Nvidia Quadro K3100m.

 

Do you think I can solve this problem with some driver fixes?

 

I followed this super guide by Jake Lo: https://osxlatitude.com/index.php?/topic/7851-dell-precision-m6800-mobile-workstation-wip/?p=64970

...but my Smbios is not the same (I couldn't find the exact model of Jake's screenshot).

Indeed, Jake in his guide says

 

When generating your own Smbios serial with Clover Configurator 4.34, make sure to use the same Board-id from the bootpack below, otherwise blank internal screen

 

Do you think that maybe I can solve this problem with some changes in the smbios or is too late?

 

thanks in advance for your help guys!

Do as stated by JakeLo and manually set your board-id to same value as found in the SMBIOS posted in the bootpack.

 

Or reuse his exact same SMBIOS but generate new serial number using the random buttons.

Thanks Hervé!

 

But this is the first time for me...

Will I mess everything if I change the smbios now?

 

Is it ok if I just do these steps?

 

10. Generate own SMBios and SSDT 

  • Launch /EFI/Clover/Config.plist with Clover Configurator (Included in Tools attached below)
  • On the left, click on SMBIOS
  • Click on the magic Wand on the right
  • Select the model most suited for your system or use same model included in bootpack, generate a new serial
  • Close Clover Config and save the file.
  • Execute ssdtPRGen.sh from terminal (Included in Tools attached below)
  • Place generated SSDT.aml in /EFI/Clover/ACPI/Patched

11. Make sure to disable hibernation as it's a prerequisite to get sleep & wake to work Ok on a Hackintosh:

  • sudo pmset hibernatemode 0
  • sudo rm -f /var/vm/sleepimage
  • sudo pmset hibernatefile /dev/null

Hi Jake and thanks for your precious guide.

 

 

I just tried to replace my config.plist file in /volumes/EFI/EFI/Clover/ with yours, but the situation is the same:

- with no args the display is black;

- with nvda_drv=1 the display is black;

- with nv_disable=1 the display works with glitches;

 

Do you think that there is a fix for this problem?

Because actually I need a working GPU for my job (motion design) and it would be great to use this laptop with OSX!

 

Thanks a lot!!

UPDATE:

I tried to use directly Jake Lo's config.plist file and the display is black.

I also tried to manually edit the config.plist file and insert the same board-id in Jake's file and nothing changes.

 

When I boot using the web drivers the display is like in sleep:

if I try (with black screen) to insert the password and adjust the volume it plays that "bling" sound

AND

if I plug a HDMI display, the system works correctly, with NO GLITCHES AT ALL.

 

So I think that the goal is to make the built-in display working.

Any advices?

 

Thanks a lot for your support guys!
