xserver-xorg-input-vmmouse – VMMouse input driver to use with VMWare
% apt-cache show xserver-xorg-input-vmmouse | sed -ne "/^Description/,/^$/p" Description: X.Org X server -- VMMouse input driver to use with VMWare This package provides the driver for the X11 vmmouse input device. . The VMMouse driver enables support for the special VMMouse protocol that is provided by VMware virtual machines to give absolute pointer positioning. . The vmmouse driver is capable of falling back to the standard "mouse" driver if a VMware virtual machine is not detected. This allows for dual-booting of an operating system from a virtual machine to real hardware without having to edit xorg.conf every time. [...]
This driver provides very comfortable mouse-handling inside VMware without having to install the vmware-tools at all. Just use ‘Driver "vmmouse"’ in the mouse-section of xorg.conf to activate it.
Notice: this feature will work OOTB on grml 0.9 if you are using grml inside VMware.
