Can't extend screen display onto second monitor after reboot Vista 64—Radeon X1900

I am reposting this with a different thread name because I now have a
quite different understanding now of what is going on. Although the
CCC interface works somewhat clumsily, when I reinstall CCC version
10.2—each time I reinstall it in fact, I am able to extend my screen
on to the second monitor. I see an icon for screen 1 and a separate
icon for screen 2 as I should and I can control the resolutions of
each monitor independently of the other. When I reboot, no matter what
I do, only the screen 1 icon appears and, although I can clone onto
the second monitor I cannot extend my main monitor desktop onto it.

Coincidentally with every version of CCC I have used in Vista 64 I
have always had to reset the resolution (it defaults to 640 X 480)
after every reboot. Now it is bad enough having to reset the
resolution after every reboot. I would hate to think that I also have
to reinstall CCC after every reboot whenever I want to extend the main
screen onto a second monitor.

I am hoping that this new information may help someone help me
understand and fix what is going on here.

Thanks in advance for any help!

Re-iterates two things for me. ;-) (Sorry - yes, I felt it should be
said.)
- Avoid ATI hardware.
- Skip Windows Vista if at all possible.

I know one of those things is almost like attacking a religion and the other
is all but a known fact. ;-)

What happens if you uninstall the video driver you have downloaded and just
use whatever Windows Vista finds for you - not from Microsoft Updates, mind
you, but just what it defaults to if you uninstall the Video card and
reboot - allowing it to install whatever and without all the catalyst
software?

After that - what happens if you ensure all the catalyst software crud is
not there at all and you just install the *driver only* from ATI's
support/download site - can you better control the monitor(s) and
resolution(s)?

Hmm--the only problem with getting rid of CCC completely is that I
frequently use its ability to rotate the display so I can proofread
long documents with my main monitor in “portrait” rather than
“landscape” orientation. I'm guessing that one can't do that in
Windows itself but perhaps I am wrong???

I was hoping for some easy registry fix that would tell Windows not to
mess around with the CCC settings on reboot but maybe that's hoping
for too much!

Thanks for the reply—when I have time I will give this a try. Any idea
how one does extended monitor mode in Windows?
 
It sounds like maybe you have multiple different versions of the driver
and/or software installed, and that somehow older versions are mixing
with newer versions. Try totally uninstalling all of the versions of the
ATI software, and reinstall only the lastest version after the reboot.

Thanks Yousuf for the thoughtful reply. This seems like a very
plausible theory. I have always uninstalled CCC before installing a
different version but perhaps I have missed something. Other than
looking in “Programs and Features” is there any way to tell whether I
have older versions of the driver and/or software still working on the
system?
