I just received an ASUS N43J notebook for Christmas. It has the dreaded Nvidia Optimus configuration: Intel integrated (using i915 it seems) and a Nvidia GT425M discrete graphics.
Everything seems to work fine on it except for the usage of the 425m graphics card. I do a fresh install, then all the updates. Afterward, I setup and use the PPA repository for the latest Nvidia Graphics Drivers
When that's complete, I go to Additional Drivers and enable the Nvidia drivers, then restart.
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update && sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings
Now 1 of 2 things (or sometimes both) will happen:
1. I will either sit on the always pleasant "checking battery state" or
2. I will be brought to a terminal w/ login prompt. Pressing Ctrl+Alt+f7 will bring me to the "checking battery state".
Booting into Recovery Mode brings me to a working desktop. If i remove the Nvidia Drivers, or rather not use them by deactivating them under additional drivers, I can boot normally, using what i can only assume is the Intel Drivers.
I understand that that this time, Linux/Ubuntu can't work with the Optimus configuration. In my extensive reading of this issue, I also understand that the Nvidia driver is not being picked up by Xorg or something.
Is there a way to disable the Intel graphics and force the use of the Nvidia graphics? My BIOS does not have an option to turn off or toggle Integrated/Dedicated graphics. Is there a way to do this inside the OS? I'm pretty well versed in Ubuntu and have solved almost all my past problems, but this one seems above me for now.
What are my options here?
Thanks for any help.
