Hello,
I'm using a dell XPS 17 laptop, using a nvigia geforce gt 555m gpu, and a intel i7 2720QM cpu.
I'm currently not using the graphical chipset on my cpu, and I always use the gpu. The problem is, it uses a lot of power, and when I use several screens, it's starting to be hot and the fan start to make a lot of noise.
So, I decided to invest some time to get my intel driver working, and then bumblebee. I tried everything I found on the internet to get it working, always resulting in: "No devices detected".
Here are some informations about my computer so I can get some help:
lspci -vvv -nn http://pastebin.com/Q0DEs2vn (graphic card at line 175)
lspci | grep VGA : "01:00.0 VGA compatible controller: NVIDIA Corporation GF106M [GeForce GT 555M] (rev a1)"
It seems that the kernel doesn't recognise my intel graphic card. But I have one: look at my /proc/cpuinfo http://pastebin.com/zruSmQNK
On the intel website, it says that I have one: http://ark.intel.com/products/50067/ ("Intel® HD Graphics 3000")
Here is my Xorg.1.log: http://pastebin.com/cTe7mXUi
Here is the result of the command cd /etc/X11/xorg.conf.d; for i in `ls`; do; echo -e "\n\n\t$i\n\n"; cat $i; done : http://pastebin.com/Bm75zkX8
Here is my /etc/mkinitcpio.conf: http://pastebin.com/1AFVcYaG
And here is my /etc/default/grub: http://pastebin.com/7SnMV6RF
I hope I provided enough informations, thank you for your help. :-)

Actually, it does not say on the Intel page that you have one:
Processor Graphics ‡ Intel® HD Graphics 3000
...
‡ This feature may not be available on all computing systems. Please check with the system vendor to determine if your system delivers this feature, or reference the system specifications [...] for feature compatibility. Functionality, performance, and other benefits of this feature may vary depending on system configuration.
Check the BIOS for an option to switch to the Intel GPU. If there's no such option, the Geforce 555M is the only GPU your system has.
