Dell Latitude E5420 Graphics Issue

[geekfly565]

I completed an install of OS X Lion using a retail copy of Lion on my Dell Latitude E5420. After completing the install, I booted the system using the verbose and safe mode flags. After making sure that other things worked, I went on to getting full resolution on my display. I booted using -v "GraphicsMode" = "1366x768x32" and now my display seems to be split in four quadrants. I am HIGHLY confused. Removing the flag fixes the issue. In the BIOS (Its actually a UEFI system with legacy support) and in Windows it works fine. I know it is not with the hardware. What do I do? I have tried to set the resolution in org.chamelon.boot.plist and com.apple.boot.plist and it does the same thing. I have included a picture for those interested.

Hi geekfly565,

I also have the same model laptop, Dell Latitude E5420. I was able to install Lion 10.8 and mavericks but the issue i ran into was network cards. Both OS did not recognize Wifi card and the net card on my motherboard. I even ran multibeast to install network drivers and other drivers as well but it was unsuccessful.

I found this post here that adding kexts seemed to fix the issue, check this out, i did not understand what it was talking about so had no choice to go back to windows again, hope this helps.

You replied to a post that is more than a year old.

As far as WiFi, it depends on having compatible hardware. What WiFi chipset does your laptop have?

Same goes for Ethernet, although there is a few open source drivers to support common PC hardware (but not all).

You need to find out exactly what device you have. Some Broadcom are supported, some not. Use DPCIManager to see what you have... Or 'lspci -nn' in Linux.

Are you thinking of attempting again?

Oh ye, i will always attempt to get it working. Right now i have windows 8.1 installed. Isn't DCPImanager for MAC OS? How can I get the exact Broadcom device I have from windows?

You can look in Device Manager, properties advanced. 'lspci' in Linux would be better.

In properties > advanced there was too many info and did not know what to get. Let me fire up a few Linux VMs i have and see if that will tell me anything.

A Linux VM won't work. That will show you devices in the *virtual* machine, not the *actual* machine. Make a Linux USB and run it directly.

Ye i did that, i ran live latest x64 bit ubuntu and here is the results.
