Re: multiple xpdm drivers on vista

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

When you talk about `virtual drivers` do you mean `mirror driver` ?
The system design should not have changed in the XPDM area.
In fact, when you have a WDDM video-card and you load a mirror driver,
the system will use the cdd.dll `XPDM` driver, and, it will load any other
mirror driver on the side.
The system ships with one mirror driver, rdpencdd.dll.
You can load that mirror driver by starting wincollab.exe,
and sharing your desktop.
Can you try to add one of your drivers while rdpencdd.dll is loaded ?
Maybe it's a problem with one of them.
The only suspicious thiung I can think of is that DrvNotify (in Vista)
is being used `more often` since cdd.dll needs
to refresh the screen using DxgKrnl.sys

Any know problems when you use multiple xpdm drivers on vista ?

Vista running a xpdm video driver (real video card) then i add 2 virtual
drivers,
this works ok on w2k and xp.

Usage:
To support 3 or 4 displays on notebooks you can't use the new driver
model,
external usb VGA, dockings with GPU or virtual video drivers over network
are never of the same chip model as the portable.

In Vista however, i can only activate one.
real+ virtualA
real +virtualB
but as soon as i activate real + virtualA +virtualB the while system loops

**driver virtual A and virtual B are indentical ( except the inf file)

-------------Start driver A (OK)----------------------

First observation
Driver B never has drvnotify.
If renamed the dll's (virtualA.dll --> virtualB.dll and B to A) just to be
sure that
drivers where identical. But it is always the driver with the lowest
screen
number that get the drvnotify, not releated to dll.

------------starting A when B is runnning LOOPING ---------------

This problem is driving me crazy, did the xpdm model changed compared to
XP ?
Does vista support 3 xdmp drivers ? any know bugs...
