Xorg failed to start :: Please help

Question

Hi there, I have been trying to start X for more than 3 days and I can't seem to find a solution to this. Sorry for my english and please can someone give me some tips on this. Here's my setup:
[root@ViruSzZ ~]# lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02)
01:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series]
I installed Intel's and Ati's video drivers. I also tried using the ati's git version but none of them worked. Here's the /var/log/Xorg.0.log without using xorg.conf [ http://pastebin.com/wb4pqz69 ] and here's the ones using xorg.conf [ http://pastebin.com/wPULBM0z ] and the logfile [ http://pastebin.com/U4MN2ByM ].
I setup the above xorg.conf because when I try to generate it I get the following:
root@ViruSzZ ~]# Xorg -configure
X.Org X Server 1.9.2

I never faced this kind of issue before. I have arch running on my desktop on GeForce 8600GT and on my other laptop with Intel chipset. Please if someone can help me with this so I can get Arch running on my brand new notebook.
Thanks and Respect
P.S."Please tell me if something else is necessary to provide"

Answer 1

Finally, I booted into DE (gnome in this moment). I needed to add the following inside my rc.local
modprobe radeon
echo "OFF" > /sys/kernel/debug/vgaswitcheroo/switch
After that gnome started successfully but the screen remained black (no brightness at all). I fixed the brightness with the following command:
echo 5 > /sys/class/backlight/acpi_video0/brightness
can someone explain why is this strange behavior ? I can manage to get all this steps automated and switch between the cards via vga_switcheroo, the only pain I have was the X server.
I am really really appreciated to this community. If there are some other tips on this please let me know.
