Category: intel Group: None >Status: Closed Resolution: None Priority: 5 Private: No Submitted By: Michael Mair-Keimberger (d3vi0n) Assigned to: Nobody/Anonymous (nobody) Summary: strange mouse behavior when connecting to kvm-sesion via vnc Initial Comment: I've a few running kvm-sessions on my server (fedora, ubuntu and winxp). I can connect to them via vnc which i enabled in kvm (via kvm -vnc). The problem is that the mouse in a kvm-window is never there where it should be. This is really annoying because, for example if i try to press the start button (in windows), most of the time my mouse is already out of the window. I always have to "play" with the mouse to reach the button. Generally its with everything i do in windows with the mouse. Its the same with the other linux-oses. It seems it depends on which point i jump into the window. Also the mouse distance between the local mouse and the mouse in windows changes while i move the mouse in windows. I already made an bug-report on bugs.kde.org, because i though it's the fault with krdc (which is my vnc client), but i have the same issue with other clients too.

The reason is that, by its nature, a mouse device reports only its relative movement, and not the absolute position. Therefore the guest OS has no idea what is the current cursor position in the host OS is. In contrast, a tablet device reports absolute coordinates, and this allows qemu/kvm to put the emulated cursor into the same position as the host one. The only problem with this method is that while it works perfectly in Windows and most modern linuxes, it will not work with some exotic OS's like Haiku or MacOS X. ---------------------------------------------------------------------- Comment By: Michael Mair-Keimberger (d3vi0n) Date: 2009-11-16 15:25 Message: wow.. thanks that really helped my. Sorry for the bug-report. I already tried a few things with my configuration, but i didn't tried that :) For me this bug is fixed, so it can be closed. Thanks for the help. ---------------------------------------------------------------------- Comment By: Michael Tokarev (mjtsf) Date: 2009-11-14 11:00 Message: If you want your mouse to stay syncronized, use -usbdevice tablet option. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2897679&group_id=180599 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
