AERO not working with T410/NVIDIA

[kingweb]

I searched everywhere here, and I couldn't find anything concrete on this.
I just got my T410 yesterday, but AERO is not working. I click the troubleshoot link at the bottom and it says that windows was unable to find the problem.
I didn't change any settings. Everything is factory default still.

Thanks, but I tried that, didn't work.

Try

net stop uxsms
net start uxsms

Might also need to see if your drivers are up to date.

Thanks, I just tried that too, but it didn't work either. I restarted computer several times too. According to lenovo update, all my drivers are up to date.
I tried reinstalling the nvidia driver and got a blue screen of death.
Still no luck.
I'm thinking maybe I should do a factory restore.

Ok, I found the problem, but I don't know how to fix it.
I am using the mini dock with 2 external monitors connected. One thru VGA, and one thru DVI. The VGA when I look in the display properties, the VGA is shown as using the intel graphics, while the DVI one shows using nvidia. 3D Acceleration is not enabled for the intel/vga monitor, and I can't find out how to get it switched on.
Why would each monitor use a different graphics card? How do I enable 3d accelaration?

After further investigating this, basically, when optimus graphics is enabled, ONLY my external DVI monitor will use the NVIDIA.
Even without the docking station, the latop screen refuses to use NVIDIA, when optimus is enabled in the BIOS.
If I disable optimus in the BIOS, and enable NVIDIA only, everything works ok.
Any ideas?

Now i'll take it even one step further. If I go into the BIOS and set it to only use integrated (intel) graphics, then everything works fine too.
So basically it is ONLY the optimus that causes the problem.
Is there a special driver for it? Any ideas?

Well, I gave up and did a factory restore. That solved the issue. So luckily it wasn't a hardware problem.

Maybe it was one of those NVS3100M driver updates that ends up breaking something; the updated video drivers seem to introduce additional audio/video/DisplayPort issues on certain systems.

Ok, now I know what caused it since I did the factory restore and had to start installing things again.
I use a docking station with 3 external monitors. 1 VGA, 1 DVI, and 1 Displaylink/USB.
When I installed the driver for displaylink, it happened again. I don't know if it is supposed to disable aero, but it does. Probably because the displaylink can not handle the graphics, etc that a regular DVI/VGA can.
I am going to try and update the driver from their website instead of using the one that windows 7 automatically installed.

That fixed it!
I downloaded the newest driver from displaylink's website instead of using the 8 month old driver that windows installed. This solved the issue.
