Voodooi2c: Catalina Beta 7

[Mateo1234454545]

On latest developer beta Catalina 7 , voodooi2c doesn't load.
Only way to do so is to use \System\Library\Extensions\IOGraphicsFamily.kext at config/plist/forcekextstoload

[ben9923]

Did you rebuild your kextcache after updating?
sudo kextcache -i /

[Mateo1234454545]

Yes , off course I did.
To be precise , hackintool shows that voodooi2c is loaded but there is no trackpad option in preferences. That happens with latest 2.2 version and 2.1.4 as well.
If the patch is applied at config everything is back to normal.

Same issue here, thanks for the solution.

How did you do that ?
After installing 10.15 my elan1200 doesn't working !

Same problem here, touchpad works after forcing IOGraphicsFamily.kext to load.

@Mateo1234454545 Developer beta 8 (19A558d) is available, have you tried it?
You'll need to attach a troubleshooting archive for diagnosis.

[Mateo1234454545]

@ben9923 , beta 7 is developer beta 8.
I can't create a debug file (catalina shows error debug) , so I sent you as much as I can. If you need something more please let me know.

I can also confirm the issue here too. I couldn't find a way to force IOGraphicsFamily with OpenCore so booted my Clover install in the meantime. Hopefully this helps find a solution in general to load VoodooI2C since us having to force IOGraphics to load or rebuild kext cache has been happening for awhile.

Kernel log and kextcache log would be helpful.
Which errors do you get? Have you tried running the debug script from your home or Downloads folder, for example?

What's the output of this command (Navigate to the directory containing VoodooI2CHID.kext)?
kextlibs -undef-symbols VoodooI2CHID.kext

Please also try building with the kexts with the 10.15 SDK if you can. Some NULL -> 0 changes are probably necessary around the code, see https://github.com/ben9923/VoodooGPIO/commit/00b138251b251a1353c6839f16f451e8bc8f7562 for example (Integer expected, while NULL is nullptr instead of 0 in the 10.15 SDK)

Having the same problem with ELAN1300, the output looks the same as the above guy's but I mostly just wanted to keep this issue active.

IOGraphicsFamily dependency is required only to support the screen rotation in tablet(mode) having an accelerometer. Most desktops or laptops don't need it now but it will become a good feature in future.

Same problem here, touchpad works after forcing IOGraphicsFamily.kext to load.

hello there, the trick works for me and the touchpad works now, but I cannot see my touchpad in the Preference. How about yours?

[Mateo1234454545]

Problem solved on Catalina beta 9.
No need for the patch anymore.

I can see it in the System Preference. I'm using VoodooI2CHID.kext. Have you tried to rebuild the kextcache?

[ben9923]

Closing as issue opener confirmed it's a macOS beta issue that was fixed in developer beta 9.
