In Linux guests that use X.Org X Window system versions 7.1 or higher (such as Red Hat Enterprise Linux 5 and Ubuntu Linux 6.10), the Workstation 5.5.x and 6.0.x, and ESX Server 3.0.x VMware Tools installer does not install drivers for X Window. Consequently, the mouse does not perform correctly. The VMware Tools installer does not yet recognize X.Org versions 7.1 and higher. Supported Linux distributions that use X.Org versions 7.1 and higher typically include working VMware video and mouse drivers. VMware Tools should automatically choose the included video driver, but you need to set the mouse driver manually, as described below.
