I installing everything like in guide. I dont want to come back to windows:) please help Its becoz of HD4000 GPU, so you might have to try dsdt patches or chameleon boot.plist properties injection to fix. If you could upload your dsdt which you're using so i can patch the dsdt to fix this. Link to comment Share on other sites More sharing options...

EMlyDinEsH Posted May 10, 2013 Share Posted May 10, 2013 I used DSDT from bootpack for np900x4c. When I using flag DSDT=0 screen is ok but sleep, etc dosent work. Here are the patched dsdt file's with different platform id's for Display test, as I can see from your dump that you got Samsung Screen with Product ID of 500 which had a big problem with EDID of the screen for a user and even overriding the EDID did not work for that user who has same model of yours but diff processor so I think this screen will not work but i'll give it a try, send me your EDID dump from windows using EDIDViewer app and i'll try to compare yours and other user whose screen did not work. Let me know about the display after trying the dsdt's I sent, make sure you rename the DSDTx.aml to DSDT.aml before you copy this to Extra folder (or) try to use the boot flag DSDT=/Extra/DSDTx.aml to try every dsdt i sent.

szuja Posted May 26, 2013 Author Share Posted May 26, 2013 I'm sorry that I have not wrote back but I had work abroad. I tested yours DSDTs today. When i start installation from USB, DSDT works number 1 and 2. Tell me what difference is between those two DSDTs. And what is next steep after install? In installation I've got resollution 1024x768:( I think normall installation of OSXLATITUDE will install normal DSDT. So how I must replace DSDT?

Administrators Bronxteck Posted May 26, 2013 Administrators Share Posted May 26, 2013 put the dsdt in the include folder inside Extra... edp will then use your new dsdt after rebuilding. for resolution edit org.chameleon.Boot.plist and put your native resolution. you can also put a copy of that in the include folder.

szuja Posted May 27, 2013 Author Share Posted May 27, 2013 I understand that EDP dosnt download DSDT? EDP using existing DSDTs in Extra folder included in installation of OSX Link to comment Share on other sites More sharing options...
