Windows – Installing drivers for switchable graphics

ati-mobility-radeondriversgraphics cardwindows 7

I recently bought a laptop that came with Windows 7 64-bit installed. I have some older (16-bit and 32-bit) software that doesn't work with 64-bit Windows, but works just fine with 32-bit. Since I also wanted to get rid of all of the pre-installed spam, I decided to wipe the hard drive and install a fresh copy of Windows 7 32-bit. I can't get the graphics cards working.

This laptop uses switchable graphics, an Intel card and a Radeon card. I first tried installing this driver from Intel, which works for the Intel card. Of course, the Radeon card doesn't work with this driver and I need it for some of the newer games I have.

I also tried this driver. Windows's device manager will recognize the Radeon card, but it will still use the Intel card. Also, even though that package says it contains the Intel driver, the Intel card still isn't properly recognized by Windows (leaving me with a nasty 800×600 resolution). On top of that, the Catalyst Control Center won't open (saying "The Catalyst Control Center is not supported by the driver version of your enabled graphics adapter")

I tried installing HP's driver then installing Intel's driver on top of it. Device manager will then recognize both graphics cards properly. However, the laptop still uses the Intel card. The CCC still won't start (saying the same thing as before) and I can't find any of 'switching' graphics cards.

Before formatting, I could right-click the desktop and click "Configure Switchable Graphics" This option hasn't been in the context menu regardless of what driver(s) I've installed. After some research, I found out that this menu entry runs the command "cli.exe Start PowerXpressHybrid" I've tried manually running this command, but I get the same unsupported message from CCC.

So, does anyone know how I can get this working? I would like to be able to switch between the Intel and Radeon. But, if there's some way to disable the Intel and use only the Radeon, that would be fine

I dual-boot with Linux (framebuffer uses the Intel, haven't even tried getting X set up yet) Here's the output of lspci

# lspci -v | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] (prog-if 00 [VGA controller])

The laptop is a HP Pavilion g6t-1d00. HP doesn't support installing anything but Windows 7 64-bit, so calling tech support isn't an option.

Thanks for any help

UPDATE: I finally got it working. After a fresh install of Windows 7, I installed the HP driver (the one linked above). Then, there's an optional Windows update I installed (don't remember the exact name, but it'll stick out). After that, graphics switching works just like it's supposed to.

Moab, thanks anyways for your help

I've had a similar problem with my laptop and I've found a trick. My problem was that the original driver is very old and I wanted an updated driver. I've called the manufactor of my laptop but they refuse to update the driver. Any new driver from my graphic card didn't work because of this onboard and discrete switchable graphic card thing. I didn't care much about the switchable options but I didn't make it work. The trick is to use the old original installer and swap the graphic card driver with a recently updated driver. AMD graphic driver is only a tiny part of the huge package with CCC and so on. This works great.
