In the presence of one absolute pointing device and one relative pointing device (e.g. one passed-through USB mouse and an emulated relative pointing device), each can be used independently, and the results will generally be additive. In the presence of two relative pointing devices (e.g. but the above configuration should make our pointing device behave a bit more like a physical machine's.Ī passed-through USB HID would work in the VM as a separate pointing device, just like it would on a physical machine with two pointing devices (e.g. The problem can also potentially be addressed by modifying the software inside the guest so that it does not make unsafe assumptions about its input device. (An absolute pointing device bypasses guest pointer acceleration settings by its very nature, while a relative pointer will go through guest pointer acceleration and host pointer acceleration, which is why it feels sluggish.) You might be able to partially correct this by tweaking the guest pointer acceleration settings. The guest mouse pointer movement is likely to be "sluggish". (An absolute pointing device allows us to "warp" the guest pointer to the correct location automatically.)ģ. The guest mouse pointer will stay wherever it was when you left the guest last time. The guest mouse pointer will not reposition itself to correspond with the host mouse pointer when you click on the guest window. (An absolute pointing device allows us to detect when the pointer is about to leave the guest window, allowing us to automatically return to the host, but a relative pointer can not do that.)Ģ. You have to click on the VM to start interacting with it, and you have to hit the Ctrl+Alt keys on the keyboard to return control from the guest to the host. This will disable "auto-grab", which is the feature that normally allows you to simply move the mouse pointer into the VM's window to interact with the VM and move it back out again to the host when you want. vmx file) to include the following line:ġ. You can turn off the absolute mouse pointer support – and give the virtual machine something that looks more like a regular mouse – by editing your VM's configuration file (the. The virtual absolute pointing device typically reports coordinates in a rectangle that is something like (0,0)-(32767,32767), and the guest OS will map that onto its screen. Instead, we emulate a graphics tablet (or really just a generic absolute pointer device) which sends coordinates in some quite large range. I would guess that the cause of the problem is that the program inside the guest is assuming its input device is a regular mouse, but VMware Workstation does not emulate a regular mouse – and for very good reasons, as you will read below.
