Vaio users black screen after boot

218 posts in this topic

Recommended Posts

Hi everybody !

 

let's start from the worst part : I have a vaio laptop :/ and looking for informations about my problem I could see that a lot of Vaio users have the same problem : Black screen after boot.

 

What works on my laptop

 

1 - Wifi (internal) - Kext wizard

2 - Sounds

3 - Trackpad - Kext wizard

4 - Keyboard

5 - Bluetooth - Kext wizard

 

What does NOT work:

 

1 - Internal monitor

2 - Advanced things that I don't know and someday will appear...hehe

 

 

I need help from someone with knowledge in DSDT to try to patch my motherboard and make the internal monitor work properly. I could make a donation to this user that MAKE IT WORK (I promise).

 

"Para brasileiros fica mais fácil de eu transferir algum dinheiro que eu ache justo, por favor não espere muito, pois é complicado..rsrs"

 

 

I can send my DSDT and or any other system related file that you guys need to performe the patch. 

 

Hint: The hdmi out video and vga out works great with ce/qi perfect. But the internal monitor seems to be dead. It does not turns on not even praying!

 

I already talked to Rehab and he said the does not know much about nvidia cards patch.

 

I think we need to mod the nvidia driver and make a dsdt to make things work properly.

 

Please let's help Vaio users. Also I want to share the DSDT code if you want this with other vaio users.

 

Thank you guys. Keep in touch !

First : to get out black screen issue , boot your laptop with an external monitor.

Then when you get desktop, see which kext is related with your graphic card and delete it ( make a backup before ..).

 

Now i guess you can boot with internal lcd. No Qe/ci.

 

Black screen is well known problem on Sony vaio. Sony have not apple compliant lcd port address.

I have a vgn-fz21 with snow leo and i have never found a working fix.

 

Good luck

I was afraid to hear that :/

 

My last chance would edit dsdt and try to get it working cause I saw that Linux users had The same problem with vaio and they fixed this configuring x11 and xorg.conf files.

 

So..I thought would be a way to hack or edit nvidia drivers to recogzine The flat panel.

 

Is there a way to make The screen working better without ce qi ? Cause when I open safari a lot of glitches happen :(

I Will do this in The morning man.. It's almost 4am in here. Walking dead here hehe.

 

I Will give you a feedback about The new dsdt..thanks and good Night.

Attach IOReg again...

 

 

man !!... i think you made some progress cause now the screen does not turn off... the internal monitor is turned on but still does not show anything... the good thing is that now when I go to system preferences I can see the internal monitor as a new display... I changed the resolution of it to see if something happened but nothing... 

 

well..I've attached the new ioreg...

IOReg

 

 

During boot ... the screen blinks between black and super black... 

 

Now I notice that I have a brightness bar when I go to system preferences... And when I change the brightness It changes the black intensity....but just black.

Boot flag:

 
<key>GraphicsEnabler</key>
<string>Yes</string>
 
Attach IOReg

 

 

 

The previous file that I sent you was using graphics enable = yes... All the tests that I did I used GraphicsEnalber=Yes on chameleon.. 

 

Now I tested with GraphicsEnabler=No and black screen on both displays.

      Hi guys,
       
      So, this little tutorial is meant to help people fix a new issue with Mojave: opening jpg files (looks like it happens with larger files, not so much with smaller ones) using Quick Look (on spacebar key pressed) or Preview app using the dedicated GPUs.
      The issue is that, when trying to open jpg files (for some reason, it doesn't occur with pngs), the pop-up window would remain in an endless loop. And from that point forward, any other app trying to open the same file, will either become unresponsive (in the case of the Preview app) or just stay in endless loop (in case of Quick Look)
       
      As a workaround, in case the tutorial below doesn't work for you, you can use Grab (built-in app in MacOS) to open said files.
       
      This issues DOES NOT occur using the iGPU. So...if you're comfortable using the iGPU, just switch to that and you should be good to go. You don't need this tutorial.
       
      This tutorial is based on @Cyberdevs' research and testing on this topic (especially useful if you're using an RX series AMD video card), and my own very limited time testing this on my rig. I just thought it would be useful to create a new thread for it so that people can discuss this particular issue here.
       
      The main thing we need to do is actually very simple: we need to enable the iGPU (integrated GPU) by default, in BIOS, while actually being connected to the dedicated GPU.

       
      With that being said, I'll just move on to the actual tutorial.
       
      For ATI (curtesy of @Cyberdevs' post here).
       
      The discreet GPU should be set as primary in BIOS and your displays should be connected to your discreet GPU
      The iGD/iGPU/iGFX must be enabled in BIOS/UEFI as the secondary GPU.
       
      I removed the DSDT Reconfigured the config.plist to and removed some flags which weren't needed because of the DSDT added the InjectATI + Ornioco Framebuffer (I removed the Orinoco framebuffer because of some weird glitches but it might be useful for other AMD GPUs if you inject the correct framebuffer according to your GPU. No need to inject anything for nVidia GPUs unless your GPU needs it) Added the InjectIntel + ig-platform-id for my intel HD530 (for intel HD 530 I use the 0x19120001 ig-platform-id) Removed com.apple.finder.plist Removed com.apple.QuickLookDaemon.plist rebuild the kextcache and reset the nvram  
      Steps 5 to 7 might not be necessary I just did them anyway, if anyone succeeded to get quicklook working without those steps let me know so I can exclude those steps.

           Also confirmed to work with AMD R9 270X on a SandyBridge rig (without an iGPU) using WhateverGreen + Lilu kexts, which also helped to solve the transparency issue along with the Quick Look problem, it also resolved the buggy Screen Capture (Command+Shift+5) issue as well. 
       
          Also, do:
      nvram cleanup kextcache & prelinked kernel rebuild reboot   
      More info on that here.
       
       
      For NVIDIA
       
      This is what I needed for my NVIDIA rig and the MSI motherboard in the signature. Your milage may vary, depending on your hardware. But, the idea should be the same regardless.
       
      Set your BIOS to use PEG (dedicated GPU) so you can boot.
      Since you're reading this, chances are that you're already connected to the dedicated GPU and the BIOS is set to PEG. So just go into BIOS and see if you're using the iGPU or the dedicated (PEG) graphics device by default.
      If you're already using this, skip to Step 3 (the part AFTER Reboot). Reboot (I think you don't necessarily need to boot into the OS...but you do need to reboot at least until Clover UI) Reboot back into BIOS and set it from PEG to IGD (integrated graphics) WITHOUT removing the cable. Reboot again.  
      The result should be that the OS is tricked into thinking you're booting with the IGPU when in fact you're using the dedicated GPU.
       
      You will also need to patch the iGPU from Clover config.
      1. Graphics -> Inject Intel (UNCHECK Inject Nvidia or ATI if it's checked).
      2. ig-platform-id (in my case for Intel HD 4600 Desktop) it was: 0x0d220003
       
      And use IntelGraphicsFixup.kext in Clover/kexts/Other. In my particular case, without the kext, I would get freezes in Safari.
       
      This might be a bug with Mojave and it could be fixed by Apple in the future. but in the meantime, feel free to use this if it helps you fix the issue.
       
      Cheers!

      Hi everyone,
       
      I was able to successfully install OS X High Sierra on a 8700k with a GTX 1080Ti
       
      Everything seems to be working fine but I've been reading on other people suggesting to make sure hardware acceleration *is* working fine.
       
       
      I installed the web drivers for nvidia (and disabled SIP after installation)
       
      Web drivers version: 387.10.10.10.35.106
      CUDA Driver version: 396.64
      OS X system version is 10.13.5 (17F77)
       
       
      After installing the latest CUDA drivers, I was able to select the GPU option in "ray-trace" in After Effects (preferences > previews > fast previews > GPU Information...)
       
      I'm not sure how else am I able to test whether the GPU acceleration in other applications is enabled and running properly?
       
      PS: I don't have final cut pro so I'm unable to test that application...
      PS 2: ig-platform-id in config.plist is set to 0x59120003
