I use Toshiba M645 Laptop that has two graphic cards
with NVIDIA Optimus Technology. (Auto-swicthing graphics processors)
Now I have some vga problems and driver questions below:
1. Intel HD Graphics <-Why can't install driver from Intel official website?, driver not supports!
, but the driver in Toshiba website can be installed fine as well.
What's wrong with that? Was it mean "Intel HD Graphics" has more than one type, several of model classes?
or it must related to the chipset of Toshiba laptop's mainboard?
2. NVIDIA Geforce GT330M <-How to use only this vga stand alone?, I tried to disable Intel HD Graphics from device manager
and then the monitor was not in use, black screen was displayed.
So, I tried to disable Intel HD Graphics in safe mode, no black screen
, but the next normal boot it was displayed like GT330M was not in use
(can't config NVIDIA tools, it was disappeared from control panel), but it was still enabled in device manager.
Now, I just updated Intel HD Graphics driver, a mouse lag in Aero themes taskbar effect was fixed,
also the video framerate fault was fixed too.
Hope someone can give the solutions, how to fix these problems.
Thanks in advance.
