ATI/Intel (Hybrid) Doesn't work + HDMI

Hello, Good Afternoon.

I unfortunatelly have a problem with Kali around 1 month and I still can't find a solution. I'm almost going crazy rsrs.

I've a DELL with 2 graphics cards: an onboard Intel (Intel HD Graphics) and an offboard Radeon HD8800 ati:

# lspci | grep "VGA"
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 09)
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus PRO [Radeon HD 8850M]

I'm trying to install the ATI hybrid graphic driver but still without sucess.

I wanna put a second monitor extending (dual head), now I just got a mirror (reflect monitor).

Can please anyone help me?

Too much thank.

Hi.
I have almost the same hardware and the same problem i think. Dell precision M4800

00:02.0 VGA compatible controller [0300]: Intel Corporation Haswell Integrated Graphics Controller [8086:0416] (rev 06)
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Radeon HD 8800M Series [1002:6821]

Tried installling the propriatary AMD driver, but it will not install.
Error i get is "DKMS part of installation failed"

Also I tried to follow this guide, "Install AMD ATI proprietary fglrx driver in Kali Linux 1.0.6"
Link: http://www.blackmoreops.com/2014/03/...i-linux-1-0-6/

I am running Kali 1.0.7 so that may be the reason.
So if anyone has a hint on how to solve this would be much appreciated.
Thanks.
