Dell XPS L321X - El Capitan / Sierra Install

[Jake Lo]

Flickering re-occurred again on the second system after sleep / wake. You have the same CPU as mine, are you able to get sleep working yet?

 

Yeah, tried the ApplebacklightInjector.kext + SSDT-PNLF.aml + hotpatch, that didn't work for this system. Worked fine on my Latitudes.

If i choose sleep from the menu bar, it will sleep and wake up without issues.  It will not sleep on lid close though, it will only turn the screen off and back on when opened.

[Jake Lo]

I think sleep is slow on this system, how long did you wait? Once sleep the front LED blinks really fast.

Don't need the HDAEnabler, just need to enable layout-id = 28 which you have on the Config by theSuffering. His config has patches for ALC275 twice, I don't that would be the issue, but I need to see the output after your ran the permission fix and rebuild cache.

Please post the output here for review, could be they didn't run successfully.

Here are my results:

[Jake Lo]

Not seeing AppleHDA_ALC275.kext in the output.

Did you install it to /L/E or /S/L/E?

[GatorGeek]

In S/L/E

Wrong Place?

[Jake Lo]

/S/L/E is fine too but for some reason it 's not caching

Try removing it, repair permission and rebuild cache.

Re - add it to /S/L/E. You should get a popup error message. Click Ok.

then run permission fix and rebuild cache again.

Verify the kext is showing in the output

[GatorGeek]

Not appearing in the output

It does not look like you repaired permissions as instructed by JakeLo. Don't use Kext Wizard, do it manually.
