Lenovo Edge E420 - Display / Graphics problem Intel HD 3000

Question

Hello everyone,

?

This is my very first post. I have problems with Post installation, a Graphics issues but before that I would like to give more information about what I did first. Hopefully if this issues solved, my post can serve as a starting-points for others with the same machines. I will change the subject tagline according to the current issue I'm pursuing / trying to fix.

?

I. My Build

======

Laptop : Lenovo Thinkpad Edge E420, Intel ?i5-2430M CPU @ 2.40GHz. mSSD KINGSTON SMS200S3120G 120GB. GUID partition. 8GB RAM.?

Installer : N{censored} Mavericks 10.9, via USB boot installation

Bootloader : Clover EFI, installed using Vietnam tools?

Clover tweaked using latest clover configurator

?

II. Working (using additional fix and kext from the installation) :?

  1. Keyboard : Standard international (fn not worked atm)
  2. Video : Using only AppleIntelFramebufferCapri.kext, buggy
  3. Audio : Patched (fixed ?) out of the box during installation, I don't remember which kext does this
  4. Lan : Using RealtekRTL81xx.kext
  5. Touchpad :?Patched (fixed ?) out of the box during installation (basic mode)
  6. Battery management : seems to work fine for now, indicator is fine.
  7. Detected as : MacBook Pro 13 inch early 2011
  8. Bluetooth : haven't tried it, but its detected

III. Not Working / buggy :

  1. Keyboard : fn not working atm, but minor issues for now
  2. Wifi : Centrino Wireless-N 1000, using LAN only for now
  3. Trackpad pointer : the thinkpad legendary red pointing devices, using external usb mice and keyboard for now
  4. Display / Graphics Video : the current pressing issue for me, stuck with default 1024 x 768 resolution

IV. Files I attached within this post to help with investigation / troubleshooting :

  1. kexstat.txt - all loaded kexts per this post
  2. clover's config.plist from EFI partition
  3. ioregdump.txt - from "ioreg -l" command
  4. current patched DSDT.aml
  5. DarwinDumper generated files
  6. Display files (patched edid.bin and patched override files) I created in an attempt to override display problem using FixEDID program, this Guide, and this Guide

?

Current issue : Display Graphics

Right now I'm stuck with default 1024 x 768 resolution, I followed the guide I mentioned on point IV. 6. above, but still no avail, my Display Preferences only got that one resolution and no other resolution choices nor scaling available.

?

Before patching edid, my "ioreg -l | grep IODisplayEDID" is not showing anything but now it shows the value of my current patched EDID, so I think I'm on the right track on following the guide, just wonder where do I get it wrong.

?

As additional info, playing youtube and videos using Chrome browsers is fine (though glitchy, its playable, both sounds and video), but playing normal Video files is not working, I mean its played, the sounds come out just fine, the player can play the Video just fine but no video, its like the video is hidden /blank (tried both using VLC and MPlayerX).

?

If there are any more info needed, please tell me. Any little clue of information will be much appreciated.

?

Best regards,

apronouva
