display brightness and Aero - RC1 on Toshiba laptop

[Alexandru Pojoga]

Hi all,

I've installed RC1 (5600) on a toshiba qosmio laptop; although Vista
defaulted to "standard VGA", fortunately the manufacturer's display drivers
for Windows XP installed on it without complaining.

However I can't adjust display brightness from Control Panel -- except in
three big jumps: 100, 40, and 0. The display had at least eight brightness
levels available in XP. While the brightness slider from Control Panel at
least works, the one in Power Options doesn't do anything at all.

thus, Question 1: which driver is responsible for the actual display panel?
The display driver? The monitor driver?

Also (this is an nVidia Go 6600), the nVidia properties panel somehow
reports DirectX 8.1, even though it used to reporte 9.0 in XP with the same
software. Downloading and installing DirectX 10 from microsoft.com didn't
change anything. dxdiag reports DX10, but the nVidia panel still says 8.1.
I'm guessing this is why I can't enable Aero, and Graphics has a 1.0 score
in the Windows Experience Index.

Question 2: any reasonable way to force it to use DirectX 10? This is a
rather high-performance graphics card. (the chipset is Intel 915PM Express,
if that helps).

Overall, Vista is just gorgeous and performs nearly on par with XP, even
with all the default services still running. The user interface is just...
polished, thought out (the new behaviour of the Start menu alone is worth
all the money). Kudos to the developers and designers.

Thanks all.
Alex

If a video card is not designed for directx 10, you will not be able to use
directx 10. A new video card will be necessary.

How do you change the brightness? My Sony Vaio laptop, I could change the
brightness under XP, but not under Vista, I was waiting for Sony drivers
to acheieve this, but perhaps Vista has this, and I havn't discovered it...
