   We've just started upgrading to 4.1.1, and most things seem to work great.
   However, the SunView mouse pointer (the arrow) doesn't go away when we
   exit SunView. It stays on the screen until we enter SunView again. This
   isn't too bad on the console, but it's very annoying when we start up MIT
   X Windows (X11R4).  We haven't tried OpenWindows 2.0 yet.

I've experienced the same problem both with SunView and OpenWindows 2.0
immediately after installing the GFX patch from sun.  It appears that both
of these programs take "advantage" of the hardware cursor support
avaliable with the GX board, but fail to turn the cursor off when they
exit.  The following bit of code will turn the cursor off.

#include <stdio.h>
#include <fcntl.h>
#include <sys/ioccom.h>
#include <sun/fbio.h>

main()
{
  int fd;
  struct fbcursor curs ;

  curs.set = FB_CUR_SETCUR;
  curs.enable = 0;

  fd = open("/dev/fb", O_RDWR);

  ioctl(fd, FBIOSCURSOR, &curs);

  close(fd);
}
