[Help] Thinkpad T540p lock screen and sleep problem

2880x1620 is a bit of a strange resolution for internal laptop display.
Are you certain?

But if so, it borders on HiDPI, which will require larger DVMT-prealloc (typically 128mb), framebuffer patch to match, WhateverGreen.kext with -cdfon kernel flag.

Yes, I am certain. Its a 3K Display. The first one i ever saw.

Let me check WG.kext with the flag

Must also have 128mb DVMT-prealloc and framebuffer patches to match.
Refer to config_UHD.plist in my y50 github repo for hints.

Hey bro i also have the f**in 3k Display and got my Laptop booted the last Time on Sierra... since then tried to get it to work for like 80 hours and finally gave up like 6 months ago... is yours working? If so could you tell me about your config and kexts? Do you have unlocked bios? I do so but i just couldnt get it to work. The optimus gpu and the 4 series intel cpu is just like seriously worst case
 
I tried on my W541 to use nosleep utility 1.5.1, and found out:
  • when closing the lid, the 3k display goes black
  • no sleep while the lid is closed
  • screen wake when lid open again (it doesn't go to black screen or flicker screen with black background)
  • sleep from menu the doesn't work (have to use hibernate 25, and close the lid before system power down is completed)

Hallo,
Everything is working on my lenovo t540p except display off for long time. Everytime I close display for 1-2 minutes and open it again it works fine but if it is closed for longer it stays black. Here is my efi folder attached. Please for a little help.
