Hi RehaMan, I am trying to find a patch for my XPS 12 with eDP screen connector, mainly for screen wakeup. It is not easy but I may have a clue now. I made two configurations to boot up Sierra and the IORegistry files are attached. Ig-Platform-id is set to 0x01660003 for both. One is patched...

This is challenging. Do you know if anyone has done something similar?

I understand the difficulties but I am very close. Hope you can point me to the right direction with the following observations. Based on the current clover folder, if 01660003 is used, everything works except no image on the built-in display. Although no image, I can see backlight turned up...

The trackpad seems to be too sensitive and I changed two default settings. Dragging Pressure increased from 80 to 120, and Filter pressure from 20 to 80. I do not experience mis-fire anymore with the changes.

Hi Rehabman, I have made almost everything working for my xps12 except one issue: black screen after wake up from sleep. The laptop has eDP connector with HD4000 and I do not expect brightness control to work. Now sleep works well but not wake up. Here are what I have done: 1. Cleaned up clover...

No. Backlight control is not going to work with displayport according to Rehabman. You may use Shade to control brightness; http://www.charcoaldesign.co.uk/shades . Current issue for my xps 12: screen stays dark after wake up from sleep.

Yes, I did. My xps 12 came with displayport so I had no choice but to make it work. I uploaded my clover folder a few posts back if you need.

You're welcome. I disabled 4,5 finger gestures and horizontal scrolling. They are not useful for me and may cause unintended actions. If you like I may put them back. I also found the trackpad works better in osx than Windows. In osx with this driver the trackpad is smoother and more...

Glad to know the driver works for you as well. The laptop is good running OS X, but I feel not so good when the trackpad acting like mouse. I really like to have tapping and 2-finger scrolling. That's why I spent quite some time on the driver. It's great to finally get both tapping and...

I corrected some issues in the cypress trackpad driver and it works better now.

Spent sometime to understand how the trackpad packet works by examing the cypress driver code. The issue was the inconsistancy in numbers of bytes 0x0 between finger touches. This resulted in shift of header byte. The pad also sends randomly a stream of 0x01 during dragging. I modified the...

Many xps12 users with cypress trackpad reported the same issues, while xps13 and others said the driver worked well.

Following your link, I was able to find out debug information. The problem is cypress trackpad acting erratically, freezing any jumping, after a few seconds in use. Reading debug information, I realize the trackpad firmware on xps12 sends out irregular packets when problem starts. A normal...

Compiled on El Capitan and tested on Sierra. With the new log mechanism, where can I find the log information? Thanks,

OK. Reading another thread, I realize the cypress ps2 driver never worked for Dell xps 12. Bugs were always there for the previous versions of osx. I am trying to debug now. I compiled voodoo ps2 driver with cypress trackpad and can reproduce the issues others had reported. However, the debug...
