When I try to use a (Linux) VM via vnc there appear to be two mouse locations at once. One is the pointer displayed on the screen; the other is the shown as a little box by krdc when I select "always show local cursor" in the krdc menu. It also appears when I use xtightvncviewer. The two locations are linked: moving the mouse moves both. However, the relation is sloppy, so that even if they two locations start the same they quickly become different. The pointer on the screen is the "real" location as far as the VM is concerned; if I want to click on something inside my session, the pointer has to be over it. However, the alternate pointer controls whether my mouse is considered inside or outside the VM. So if I move the mouse so that the alternate pointer is outside the screen, my real mouse jumps outside of the VM. This is basically unworkable; since I see it with 2 different clients I suspect the issue is with the VNC server, i.e., kvm. Does this ring any bells? Is there anything I can do to improve things? I'm on debian lenny with a 2.6.30 kernel, kvm 72, amd64 architecture. The VM is running the standard Lenny 2.6.26 kernel and KDE 3.5.10 (same KDE as on the host machine). Everything is happening on one physical box. I noticed some kvm only (not qemu) bugs about VNC display (e.g., https://bugzilla.redhat.com/show_bug.cgi?id=503156), but the seem to describe different symptoms from mine (though I think I've seen some of the tearing they describe as well). I'd appreciate a cc, since I'm not on the list. Thanks.
