I've got a Dell XPS L502X and I'm having problems with Windows Aero enabled and the Integrated Graphics driver crashing and reloading.
I've configured the laptop to run everything on the NVIDIA graphics in the Global section, and the issue seems to happen when using AutoCAD 2012 LT (which has been configured to run on the NVIDIA card in the individual applications section as well).
I can't seem to force "dwm.exe" (which I believe is responsible for Aero) to use the NVIDIA card; has anyone got any ideas?
I'm using the drivers available from the Dell website, although I've noticed that NVIDIA have a later version out, so I'm going to try that.
I've looked in the BIOS and can't seem to find any options to switch Optimus on or off.
Has anyone else experienced similar problems; or managed to force absolutely EVERYTHING to run on the NVIDIA card?
I'm not concerned with battery power, this is essentially a desktop replacement machine anyway.
For the time being there is no way to disable Optimus from the system. It looks like you have done the most that you can by configuring the Nvidia card to be the default GPU Globally.
This seems to be an Nvidia wide issue with AutoCad and Optimus
I don't know if there are plans any time in the near future to put in an option to disable Optimus in the bios, but if I hear of one I will certainly post on the notebook forums.

AutoCad and Maya and other 3D apps use Quadro GPU's or FireGL GPUs not Geforce or Radeon.

I think we've got a bit side-tracked and maybe I wasn't clear enough...
AutoCAD works absolutely fine, so long as Windows Aero is off (i.e. the "Windows 7 Basic" theme is used in "Personalize".)
This is not acceptable for the end-user, and I'm trying to find a way to force AERO (and not AutoCAD) to use the NVIDIA graphics.
So far I have tried the following:
Set the Global setting to the NVIDIA card
Set AutoCAD's .exe file to use the NVIDIA card
Set Windows Explorer to use the NVIDIA card
When I try forcing DWM.exe to use the NVIDIA card the option is greyed out and unavailable.
Has anyone got any ideas on how I might be able to force AERO to use the NVIDIA graphics card?
Depending on the App. you use,Windows AERO is turned off by the GPU hardware itself because it does not function with the hardware drivers.Most cases AERO stays on unless the hardware itself turns it off.I know it works that way with my GPU and certain Apps. i use.

XPS Gen 4 Desktop>being rebuilt
I just updated my post on Optimus.
There is a Optimus FAQ from Nvidia that may be of some help for you.
Dell has just recently posted an article on configuring Optimus that may have some info that you may not have been aware of.
<ADMIN NOTE: Broken link has been removed / replaced from this post by Dell>
Again, if there are any plans of a future BIOS update to allow users to disable Optimus I will report here.
