ASUS X99 gIOScreenLockState Error

[HappyDuck13]

Hi all,

I was upgrading my Asus X99 build with the 5820k and an Nvidia 960 GPU. I had it booting to Yosemite and I got it booting into Sierra, but when trying to get bluetooth working I had to reset everything. Now when I try re-installing using the same guide I am running into this error when I boot up.

IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0

Not sure what to try at this point. I have rebuilt my installer USB drive several times using different computers and re-downloading Sierra.

Any suggestions would be appreciated!

I have the same problem (Z170I, i7 6700K, GT 1080) after clean install of 10.12.4 and Nvidia Web Driver.

Can only boot with boot args "nv_disable=1" but then the graphics card is not used, only software emulated (and slow) graphics. When I remove the nv_disable=1 the boot process reboots after the IOConsoleUsers etc. message. The Web Driver gets not loaded.

Have been looking around for solutions but didn't find any.

Setup emulated NVRAM to store the nvda_drv=1 boot flag in boot-args.

Thank you for the hint. Actually I followed solution of problem 6 and checked the NVRAM (with NVRAM -xp in the terminal) and it seemed ok. Or should I check for a specific value in the output of that command?

Haswell:~ BreBo$ sudo nvram nvda_drv
nvda_drv    1%00

Hi BreBo,

checked now the NVRAM and it shows the "nvda_drv 1%00".
So it seems the NVRAM ist not causing the problem.

Any more hints? Do you need more data about my configuration?

many thanks

Check your config.plist

Boot > Arguments > nv_disable=1 should be disabled



Graphics > Inject Nvidia should be disabled



System Parameters > NvidiaWeb should be enabled

I am still at the MacOS installation stage so I need to have nv_disable=1 checked.
I have tried resetting my settings on the motherboard and clearing the CMOS.
I have also re-downloaded and reinstalled the Sierra USB several times, but I am still seeing this same error.
I also tried both an Nvidia GTX 960 and a 1080ti so I don't think there is any issue with the graphics card.

I have Inject Nvidia disabled and Nvidia Web Driver enabled. When I disable NV_Disable I can't boot and end up with
the gIOScreenLockState Error and rebooting. See my config-plist attached.
