I wrote the driver of my video card in XFree86 4.2.0. The hardware cursor works well. \
Then I upgrade my driver in order to run in Xorg 1.3. I found that the hardware \
cursor didn't work in Xorg 1.3. I tracked the source code of Xorg. In function \
xf86SetCursor in "\hw\xfree86\ramdac\xf86HWCurs.c", the following codes are executed. \
  if (pCurs == NullCursor) {
 (*infoPtr->HideCursor)(infoPtr->pScrn);
 return;
    }
 
I think normally the above codes should not be executed.
 
Any comments on this problem will be appreciated!
