Well, I did a bit more investigation and put a printf into the function sdl_send_mouse_event in sdl.c to see what was being sent from the Host OS to the guest OS. It would seem that the SDL_GetRelativeMouseState function is reporting odd values for dx and dy on my laptop but not on my other machine. Both of them are running the same OS for the host OS, Fedora Core 3. One is a normal computer with a PS/2 mouse and the other is a laptop with a Synaptics Touch pad and a USB attached mouse. The laptop actually has both devices going through GPM which is set as a repeater in PS/2 mode. So the data being sent to xorg should be PS/2 data. Thus the data that SDL is getting should also be PS/2 data, but from the look of it, it isn't. From the look of it, it should be reporting small changes either a small positive value or a small negative value. On my laptop it actually jumps all over the place.... but it's usually large positive values. I have more investigation to do but it might be something like a buffer not getting written write or getting written with junk data. Juergen, what type of pointing device do you have? -- Jason <[EMAIL PROTECTED]> _______________________________________________ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel
