DxgkDdiSetPointerPosition not getting called in WDDM Miniport Driver RRS feed

  • Question

  • Hi all,

    We are implementing hardware pointers for a WDDM display driver on Windows 7.  In my DxgkDdiSetPointerShape function, I am making copies of the pointer structures and returning STATUS_SUCCESS.  But after that I am not seeing calls to DxgkDdiSetPointerPosition.  Is there something else I have to do other than return STATUS_SUCCESS in DxgkDdiSetPointerShape?  Any ideas why Windows wouldn't call my DxgkDdiSetPointerPosition function?

    Thanks

  • Ok, I made some progress and here is what I have got so far:

    When the driver is loaded and i do a reboot, as the log in screen comes up, i see the calls to DxgkDdiSetPointerShape and subsequently DxgkDdiSetPointerPosition.

    Now  it appears from that the pointer is not set to visible because I see the value of pSetPointerPosition->Flags.Visible as 0 in WinDbg.
    So the new doubt is: How to make the pointer Visible??"

    Thanks!
