[Julienanglet]

Very good news @CoBrA2168 ! thank you very much for your work.

I can do it with clover configurator ?

You have a problm like me on touchscreen ?

Hi @Sniki,
Thank you very much, backlit on Keyboard and F7 to F12 work very well !

It's upgraded touchpad https://photos.app.goo.gl/QQaiRZsB8xHF2DTd9
Same problm with your VoodooPS2Controller.kext or modified version ...

Can you try to save SSDTs as aml on included hotpatch folder individually instead of SSDT-T440S.aml and add them at EFI/Clover/ACPI/Patched. (Skip ssdt-t440s).
You have a patching error somewhere occuring on ACPI for some reasons, will check on weekend and try to fix that.

@Sniki and @Julienanglet - just finished my testing. The fix was simple - add back the con1 and con2 frame buffer patches to config.plist (linked in the commit log above). Not sure why our machine needs it and your X230 doesn't, but I confirmed that DP to HDMI, VGA to VGA, as well as HDMI audio is now again working.

Thanks for testing @CoBrA2168 I will add them back. (Its a Thinkpad X240 btw not X230)
Can you test if these values are enough:

framebuffer-con1-enable <00010000>
framebuffer-con1-type <00040000>
framebuffer-con2-enable <00010000>
framebuffer-con2-type <00010000>

The -igfxnohdmi boot argument should've been enough but still if it fixes the problem, it's all good by me.

hello @Sniki
ok i test to compile each files present on hotpach folder
for skip ssdt-t440s, i remove it ???

For

framebuffer-con1-enable <00010000>
framebuffer-con1-type <00040000>
framebuffer-con2-enable <00010000>

Remove SSDT-T440S.aml from EFI/Clover/ACPI/Patched
Save these SSDTs on hotpatch folder as .aml file:
SSDT-ALC3232
SSDT-BATC
SSDT-LED
SSDT-KBD
SSDT-USB
And place all these 5 .aml SSDTs into EFI/Clover/ACPI/Patched.
For framebuffer values.
Clover Configurator > Devices > Properties > PciRoot(0)/Pci(0x02,0) and add the values there, set these as data
Reboot and see how it works.

I can test again today with just the "enable" and "type" framebuffers. Right now I think one of the has a "alldata" field as well. I double checked and I do have -cdfon and -igfxnohdmi added as well but I guess those patches are still needed on some machines.

@Sniki i do modifications. (you find new debug on joint file)
Same problm with trackpad and touchscreen, nothing change.

For hdmi problm, I test it in my office in 4 hours

Thank you very much for your help

i don't know if it can help you, i have this message when i compile SSDT-BATC

@Sniki
sorry not working with

@Sniki
sorry not working with

Sorry i did give you wrong patch data values.
i gave you wrong patch data for framebuffer-con1-enable, for framebuffer-con2-enable and framebuffer-con2-type
I was at work and replied from my Phone.

1.Change the patches i did give you to this:

framebuffer-con1-enable <01000000>
framebuffer-con1-type <00040000>
framebuffer-con2-enable <01000000>
framebuffer-con2-type <10000000>

Now it should work.


2. But just in case if it doesn't work again, remove framebuffer-con1-type and framebuffer-con2-type and add these two patches.

framebuffer-con1-alldata <01051200 00040000 87000000>
framebuffer-con2-alldata <02041200 10000000 87000000>

Now it should work.

 

[Julienanglet]

hihaaaaa !!!!! , if i add

framebuffer-con1-alldata <01051200 00040000 87000000>
framebuffer-con2-alldata <02041200 10000000 87000000>

hdmi out work very well !
thank you @Sniki

For trackpad and touchscreen problm, you have an idea, something to test ?
