I will try to find any upstream bug report. If I might be able to.

** Description changed:

- attaching all the following files into my 1 attachment ::
- dmesg > dmesg.log
- sudo lspci -vvnn > lspci.vvnn.txt
- cat /proc/version > proc.version.txt
- uname -a > uname.txt
- lsmod > lsmod.txt
- sudo dmidecode > dmidecode.txt
- /var/log/syslog
- /var/log/kern.log.0

+ The Alienware m11x has two GPUs, an Intel integrated graphic card and a
+ Nvidia offboard graphic card. In Windows, it's possible to switch
+ between the two cards using fn + f6 (something like that, I actually
+ doesn't have this notebook) on the fly. Using the Intel card, the
+ battery life is a way better. The Nvidia card is more powerfull.
+ 
+ When using Ubuntu, it's not possible to change it on the fly, it must be
+ done in the BIOS. Besides that, when using Intel card on Linux, the
+ Nvidia card remains active, drawing the battery very quickly.
+ 
+ The desired behavior would be:
+ - Be able to switch between the two graphic cards on the fly.
+ - When using one card, the other should remain deactivated, improving battery life (wich is the idea of having two cards).
